Although I have been 3D printing for over 12 years, I never found much use for a dryer until recently when I bought some more exotic filament. I have used this unit a few times and found it very effective and fairly easy to use (if you read the instructions). You can set time and temperature and monitor the humidity in the camber with the digital display. The unit is extremely quiet and it has an option to feed the filament directly to your printer. Great unit and you can't beat the value with the price point. A recommend for anyone who needs a basic filament dryer at a great price.

A great little dryer. Temps don’t get hot enough for petg, but works great for pla.

Using this thing is very confusing to start, and there are not clear instructions included. That being said, I figured it out eventually and am pleased with the results. It does have a fan inside, so the air circulates quite well. I leave a reusable silica gel packet inside to help facilitate the drying process. Once turned on, the only way I have found to turn it off is to let the timer run out. You can adjust the temperature and the timer. Theoretically, it has a hydrometer inside, but I'm not convinced that it is accurate. Interestingly, part of why I purchased this dryer instead of Sunlu's more popular model with the screen on the side is because of the forward-facing screen, but in my setup, I would have benefited from the side screen more. since the filament has to bend in strange ways to get to my printer if I want to see the screen. It is a bit noisy, though quieter than my old Ender 3 V2 Neo and my P1S. The frequency at which it operates is the annoying part; it gives me a migraine, and it sits right behind my desk. There are two slots for filament built into the dryer. One on the front top curve of the lid, and one right where the lid meets the body. This second slot has an included plug to keep humidity out, but the plug falls out pretty much every time I open it. More annoyingly, it likes to fall inside of the dryer and has almost fallen into the vent hole many times. Both slots can accommodate a PTFE tube like the spares included with a Bambu AMS. This is necessary for proper operation in my opinion as the slots by themselves are at awkward angles and risk bending or breaking filament/putting unwanted strain on the extruder motor. There are very small PTFE slices (??) included with the dryer that I believe are supposed to fit into those slots to soften their edges, but it doesn't help much. I haven't seen condensation build up inside when I'm drying filament, even without a silica packet, but I have recovered an old roll of PETG and several rolls of PLA, and now printing with TPU is much easier. All of this is to say that it does its job quite effectively, but I wish a company would be more intentional in their design process.

I live in the south where the summers can be fairly human I noticed a lot of small anomalies on my first layer especially in the summer but they really didn't fear much with the print. This it was small and compact so I thought I'd give it a try. I took one of my Older filament reels and ran it for 6 hours. The next day I used it to produce a print and the first thing I noticed was my first layer was great. So the dryer seems to be working well. I'm great I was going to downgrade it for lack of instructions as there really are none. It has two buttons and no iron off switch. When you plug it in nothing happens until you push a button. The left button seems to change the mode to change the temperature and the time and then both buttons allow you to increase Or decrease. Then hold the left button again to change temperature time. After playing with it for about 10 minutes I was able to figure out what the buttons do and how they worked but it wouldn't be nice if they put some instructions in the manual actually there is no manual but there is a chart for a temperature and time for different types of filaments. I did see a difference after he eating a spool compared to using a spool that I just would zip up in a zip lock bag so I am satisfied with the product. I have been This dryer for a couple of weeks now and I found that by connecting it to my printer when I'm printing and hitting the filament Before it enters the printing There is a significant improvement to the print. I'm using PLA and I only heated to 40 degrees Celsius as it prints And I let it warm up for at least 1/2 an hour before printing.

This little dryer is very easy to use and works as you’re running your print. It allows you to feed the filament through either of its existing channels and works fast. You can set the temperature range for your own filament and set the time you’d like it to run for. Overall, I recommend this dryer if you have a small printer such as the Bambu Lab A1 or A1 mini. A small drawback is that it’s a bit bulky and you’ll need a bit of space to set it up to effectively work with your printer.

Works as intended . I’ve been using it to dry new filaments or before storage . - depending on your preferences. It has a high to low pitch noise that repeates which can get annoying . - build quality isn’t great , it feels cheap - in the end it does its job

Oh, this version has a fan in it, which is an upgrade to the previous version, it also tells you what the humidity inside of it is. However… The fan started sounding louder than my printer after one month of use. The temperature sensor is literally taped to the heating element so you're definitely getting an incorrect reading and I believe that they're using this to their advantage. The overall design is flawed as many have set. Most importantly, you can get a much better product for this price. They know where for the moisture to escape. 55° is only good for PLA --- BUT IT DOESN'T REACH 55. Heating element gets to 55°, but because of the lack of airflow and the awful design of everything, the inside temperature will not even reach 40° realistically. Like, if you put an accurate temperature sensor in there, you won't see over 40°. You can search on YouTube a bunch of upgrades for this product, which could improve it if you have all of the materials needed. But once you consider the $20-$30 worth of crappy upgrades (and time) that you need to put into this product for it to be even a good PLA dryer, you could EASILY get a already working filament dryer for that price. I bought this product because I was uninformed and clearly some of the reviewers are as well. I thought the people that were being negative were just...I don't know. I don't know why I still bought it. Probably because of the price. I don't know. Seriously does not even do what it was designed to do. Don't get this. I also probably don't recommend the version 2, because the biggest problem is the lack of "moist air out and dry air in" Literally, the laws of science don't allow for this product to do what it was designed to do. I spent all the money upgrading mine, since the fan broke after a month and it was past the return date, and it's still a bad product! (I added double fans, accurate hygrometer and temp sensor, intake and outtake vents, timer relay, temperature controlled fan on/off - still a bad product. The heating part does not get hot enough to dry even PLA.) Please take my advice. Buying this product is literally the same as wasting your money. You're better off buying a good set of filament storage bags and/or completely new filament than trying to use this product to fix your print problems. Buy a different dryer. Save the money. Do not waste it here.

Does the job for small home set up. Does one roll at a time but with proper storage your rolls will stay dry after a few hours in this. You can have the roll in this while printing because it does have a hole to feed through but I havent tried it yet.
