  • If you need a borescope this is a great choice!
Size: 6.5mm
I’ve debated buying a borescope for a long time, but when I had to tackle an engine with excessive oil consumption I finally had an excuse to buy one. This thing is incredibly easy to use and comes with a memory card already installed so you can take photo and videos of what you are inspecting. The young man who I was helping out (by doing the repairs) isn’t a mechanic, so trying to explain what stuck oil control rings do to the inside of an engine can be tough. But with the tiny size of the borescope camera AND the ability to utilize two lenses I was able to capture some great photos. So it was easy to sit down and show him exactly what the problem looked like. I utilized a chemical treatment on the cylinders and thus was able to show him before and after photos. I really debated buying the dual lens version (it’s more expensive) over the single lens, and am really glad I did. Being able to switch lenses with the push of a button and flip between looking down at the piston or back up at the underside of the head was really helpful. I did not read or look at any instructions but simply took it out of the box and began using it. It’s VERY intuitive. So if you’re in the market for a borescope I’d highly recommend getting this. ... show more

  • Great tool!
Size: 6.2mm
This tool is surprisingly good for the price. It allowed me to find a water leak in a wall and limit the amount of damage required to repair the leak.

  • Camera works great.
Size: 6.5mm
The boroescope itself is phenomenal for the price. Great cameras with great lighting. Was able to clearly see down the length of my covered gutters. It would have been a 5 star but those 2 little black plastic attachments that came with it made a monkey out of me because the operating instructions don't mention them. ... show more

  • Great tool!
Size: 6.5mm
Works amazing for the price. The controls are easy to get used to it’s plenty bright and it can be used in a variety of places giving it great versatility. I would recommend you go slow because it can make you dizzy and disoriented from all the movement.

  • Great features and function
Size: 6.2mm
Bought this for my husband. It just so happened that within a month he had a car engine project where a camera was needed. He was very pleased with how well it functioned. He said the image is clear. He liked that he didn't have to use his phone for the images. He said the controls are easy to operate and liked that it had a long reach. He was surprised when I told him the price as he said he expected it to cost more for how well it works. ... show more
