I read the reviews and some people couldn't get the borescope to connect to phones and computers. I have mine sync with everything. Windows 11, windows 10, iPhone, and Android. It all works. Gives a good quality picture. I do recommend this product. Not the most expensive unit you can buy, but it is functional and gets the job done. I recommend this product if you need a borescope.

Like most shooters, I worry about the effectiveness of my cleaning routine and barrel wear. I could never quite convince myself to spend $300 - $900 for a Lyman or Hawkeye borescope. When I saw this discussed in a favorable manner in a shooting forum I just had to try it. $50? Unheard of. The Teslong Bore Scope arrived within 2 days and I had it working in 10 minutes. App works fine on my Samsung S9 and the clarity is incredible. My first look down the barrel of one of my .45 ACPs that always uses cast bullets clearly showed traces of leading and a few streaks (hadn't been cleaned for awhile). Moving on to rifles, I was appalled when I found bores that were supposed to be clean to have varying degrees of copper fouling. It also revealed that some of my barrels had less than perfect rifling production as well as a .22-250 showing the start of fire-cracking. Be aware that this device comes with pretty much every connection you should need. USB, USB-C and older common phone charger connection (this one is found by pivoting the USB connection metal piece downward to reveal the connector...clever!) There is also a light adjustment located on the cable module. There is just nothing to not like about this device. Every shooter should spend the nominal price (about the price of 2 boxes of factory cartridges) for the peace of mind and extended useful life of your firearms. Some people are concerned about it being made in China... from the various reviews I found around the web, this company is dedicated to making a superior product and are highly proactive concerning making their product better all the time. They have an excellent reputation of being very responsive to customer issues (though it may take a bit of time due to the distances and time zone differences). Highly recommend!

I purchased this borescope (NTG100) and it would not work with my iPhone. A quick email to Teslong and they sent me the correct cable. Apparently the cable for Android and iPhone are different. Once the new cable came in I hooked it up and viola, it worked perfectly. The images are clean and crisp, and Teslong’s customer service is absolutely outstanding. I would not hesitate to recommend them to anyone needing a quality product, backed by great customer service. Congrats Teslong, great job.

The Teslong borescope replaces a Hawkeye rigid bore scope that I've had for over 11 years. Sadly I snapped the Hawkeye scope during inspection of a rifle barrel (don't want to talk about it). To put this in context, the Hawkeye scope is over $1,100. I found the Teslong borescope on Amazon and since the reviews were 'okay' I figured for $50 I can't really go wrong. If it turned out to be junk then I could return it anyway. I have to admit that I was very pleasantly surprised by how good the Teslong actually is. I'll do a quick comparison between the Teslong scope ($50) and the Hawkeye scope ($1,100) under three headings (a) zero degree viewing (b) 90 degree viewing and (c) ease of use. Zero Degree Viewing (no mirror attached) The zero degree view from the Teslong is awful by comparison to the Hawkeye. With the Hawkeye you get a very clear and focused view of the rifling and can see clearly 5 to 6 inches of the barrel in excellent focus. With the Teslong you are lucky to see 1 inch at a time and the focus is grim. That said, the Teslong zero degree view will allow you to see streaks of copper and other fouling and can be useful for further examination using the 90 degree viewing. For zero degree viewing, the Hawkeye wins by a mile. 90 Degree Viewing (mirror attached) This is where the Teslong really excels. The quality of the 90 degree view is as good if not better than the Hawkeye. I was really surprised as to just how good it was. The images were crystal clear and the focus was excellent, though I did have to fiddle with much or how little I screwed on the mirror attachment in order to the get focus correct. Detail viewing of the barrel requires 90 degree viewing and this is what I used the Hawkeye for anyway so I was extremely pleased with the quality of the Teslong scope. Ease of Use Again, this is where the Teslong really shines. It is a 36 inch semi-rigid plastic coated scope whereas the Hawkeye (RIP) was 17 inch rigid aluminum. Using the Hawkeye, this meant that to see the full length of the rifle barrel, I to use it both from the muzzle end and again from the breach end. The Teslong being 36 inches allows me scan for the entire barrel length without the need to ‘flip’ the barrel and start from the other side. The fact that its semi-rigid will avoid the issue that led to snapping the Hawkeye (RIP). But best of all, when I connected the Teslong scope to my MacBook, fired up Photo Booth and maximized the screen, the barrel rifling was on my 27 inch screen. I can slide the Teslong scope down the barrel without looking at it but rather looking at the screen whereas with the Hawkeye (RIP) I had to keep my eye pressed against the eye viewer. No big deal but compared to the ease of use or the Teslong, the Teslong is much much easier to use. All in all this scope is excellent and for a mere $50 it is steal. I only have the Teslong two weeks and have no idea how long it will last. But when I think that I could have 22 Teslongs for the price of a Hawkeye (RIP) it becomes a self answering question. If you’re having doubts about buying the Teslong, stop doubting and just buy it. For $50 you can’t go wrong.

This thing is amazing! For the money, any real shooter who cares about their guns should get one. I really didn’t think it would be anywhere near this good, but I have wanted a Hawkeye for a long time, so when I heard good things about this I figured why not give it a try and I am very glad I did! I can’t speak to longevity since I just got it, but on its optical quality and usefulness, it is great. I will try to update this after a couple months of use so I can better speak to the longevity of it. However, it’s not perfect so let’s go over some minor drawbacks. 1) The way the angle view mirror has to be focused isn’t great. It works, but it requires a little trial and error every time you switch barrels/bore sizes before you can get it focused just right. 2) Since the shaft is semi flexible as you move down the bore the camera moves from one side of the bore to the other due to the flex in the shaft, and this makes it hard to keep it perfectly focused the whole way down the bore. 3) Again, since the shaft is semi flexible AND it has the heavy cord and connector on the end it makes it difficult to follow the twist of the barrel because after one or two turns the cable wants to twist back so it fights you as you move down the bore. 4) I don’t know if it’s the camera or what but when trying to adjust the lights it almost doesn’t work because you turn it down and you can watch on screen the camera adjust and brighten things back up or if you try to make it brighter the camera adjusts it back down. So you really only end up with more of a High and Low, anything in between and the camera adjusts and makes it higher or lower anyway. 5) The lights reflect off the mirror and blur out/reflect back again to where you can’t really see the area where the lights are pointing directly at. I don’t know how you could really fix that, and I don’t know if the Lyman & Hawkeye borescopes do it as well, but it is something that happens. And depending on how well you get everything focused and the position of the mirror you can end up seeing all 5 little spots of light reflecting off the mirror and onto the surface of the bore blocking the view of 5 individual little spots. Most of the negatives are very minor drawbacks and could very well be the same on other borescopes too. Do I think a $600 Hawkeye borescope is better? Probably. But how much better? Enough to justify being 10 times the price? Probably not! But all in all, this is a very good tool, and when you combine it with such a low price compared to the other borescopes, it makes this a home run. If you care about your guns and want to see the condition of them without spending a small fortune then don’t hesitate to get this.

As a firearms collector this is a must. Instead of just looking down the bore I can put the Teslong on borescope down there and see just exactly what's going on. It works on my computer and my smartphone all I have to do is turn on my camera hook up the scope and it comes right on. I can even video it make a video. I highly recommend this The Price is Right too and no APP needed.

I was really pleasantly surprised. I had used other bore scopes before but I always had to borrow them the few times I wanted to take a look at the bore. Not that I'm obsessed with looking at the bores on my rifles but rather that an occasional inspection can be a good thing to confirm barrel condition for frequent use AR platform rifles even though its likely not needed unless you suspect a problem but the technology is there so why not use it occasionally. For years I told myself I would get my own bore scope, so finally got around to buying my own. Value: Its a great value. Reasonably priced, good quality and workmanship. Use: Works as advertised and expected. Packaging and Contents: Suitable for the components, and the zippered case is nice. It did not come with a lens cleaning cloth for some reason. Basically just about everything 'optic' in the gun world comes with a lens cleaning cloth so I was a little surprised it didn't come with one, but no problem as I have a bunch of them collected over the years from firearms optics, cameras, phones, eye glasses, sun glasses, trips to the local gun store where they just give them away in a big bucket on the end of a counter, etc... so there is always one around I can use. For firearms, those little lens cleaning cloths supplied with optics tend to get soiled a little over time so I keep some fresh ones around. The manual is straight forward, instructions easy to understand, but other than the particulars about the app for Android devices and use on Windows computers the thing is pretty much self explanatory but take a look at the manual anyway. Set up and use: Basically, its a 'plug-n-play' kind of thing but if using on an Android device you need to get the app (see the manual). Initially I could not use it on my personal Android phone because its got an Otter case on it and that case has some plastic that encloses the port where the bore scope will plug into and the connector supplied with the bore scope is about 1/16 of an inch too wide to allow the connector to plug into the phone with that Otter case plastic in place and I did not want to remove the case. But I did try it with another Android phone without a case and it worked perfectly with the required app (outlined in the manual). I also tried it on a Windows 10 and Windows 11 computer, these have a built in 'camera' app and it worked perfectly with that and there is no separate app needed. Operation: Simple and straight forward. Its a bare bones basic bore scope, but its image quality surprised me some. Image is clear and sharp, and as shown in the videos with this item page on Amazon - which is about the same with other brand quality bore scopes. It had been a while since I last looked at my barrels insides like this, I was surprised at how effective my cleaning was since I last looked and only saw a few fibers left behind by cleaning patches. Barrels are in good shape. Advice: There is a little removable black cover for the camera. I recommend you hang on to this and put it back on when you are done using the bore scope to protect the camera. The cover also fits over the mirror attachments so you can leave one attached and slide the cover over that and its long enough so it will cover the mirror and the camera lens. The flexible camera cable is kind of springy and tends to want to 'un-coil' when you try to coil it back up to put it in the case, one of the twist ties with the USB cable can be used to secure it so it doesn't uncoil.

I used the Teslong bore scope to inspect my 300 RUM, mostly for throat erosion and copper fowling with clear images. It showed the lead fowling results left after my last shooting session from my cast bullets an home make lube in my 44 mag lever action. If you are an AR person this would be great for gas port inspection. It works great for inside shell inspection of flash hole and wall cracks that can't be seen from the outside. Mine came fast and as said on time. It came with 3 90 degree mirrors and there is a jam nut on the camera threads the lock the mirror in position for fuccus adjustment. I give this 4 stars because while the camaera cord is fairly stiff and pushes through the bore no problem it is a bit of a pain to angle and hold the camera in the angle you want when inserted into big bores like 44 mag or 45-70 due to diameter difference and holding in position for focus. Of course 3 days after I bought mine I found a teslong bore scope with metal tube. For what I am doing this will serve my needs. The directions say to down load endoscope app. Several popped up so I down loaded the first one I saw. All of them have 2 star ratings but for endo scope use the one I have works good. So I wouldn't worry too much about that. I use this scope on an LG 6 (VS-988T) and works good. One little thing that sucks even though the light is adjustable it still reflects off a shinny bore and can be a pain to move the camera around for a good viewing angle from the light. My phone keeps auto adjusting to the light as you change the brightness and I haven't figured out how to stop that while in the app. I would say bang for your money it is an excellent purchase. There is a wireless version available for a few bucks more and one with metal tube if want want a bit more convenience and not have to worry about spinning the cord during inspection. I posted a few picks one with what a shell flash hole deburring tool did and a video of the leading in the cornner of the groove and lands on my 44 mag.
