    • Nice and Functional
Keeps filament dry while printing. Only very minor issue for me, is forgetting to open and close small vent on top.

    • Brings dryer functionality to the Gen 1 AMS - must have upgrade
For those of us on the original Gen 1 AMS, this is a welcome upgrade. The newer AMS has built-in drying and now we can get that functionality too. Installation is easy, maybe 20 minutes, and it requires no permanent modifications to the AMS. It even comes with a long hex wrench. Best part is it works while you're printing, so there's no downtime waiting for filament to dry. Nice added benefit is that it actually dries my dessicant too. Just select your preset, let it run, filament is dry, everyone's happy. My only gripe is the vent could be bigger and ideally there would be a a small fan to actively exhaust the warm, moist air out. It works without it, but that would make it even better. Still, this beats having a separate standalone filament dryer sitting next to your printer. Much cleaner setup. ... show more

    • Works as advertised
Seems well made, works as advertised, I do wish the vent was automatic versus manual, seems a bit strange they didn't put that into the process, heats well so far.

    • Game changer
An excellent addition for anyone printing in humid environments. It keeps filament dry during long prints and has noticeably improved print quality, especially with moisture-sensitive materials. Easy to install and works exactly as advertised.

    • A steal at $50, but have a magnetic tool ready.
I’ve been waiting for this to go on sale for a while, and at the $50 price point, it was an absolute steal for my Bambu Lab AMS. It’s a great upgrade for keeping filament dry and ready to go. The installation is where things got a bit frustrating. The hex screws were a major pain to remove and reinstall, largely because the included hex tool isn't magnetized. I found myself dropping the tiny screws constantly, which is never fun when you're working in tight spaces. I eventually had to grab my own magnetic screwdriver just to get the screws into the holes before tightening them down with the hex tool. Once it's actually installed, it works exactly as advertised and fits the Gen 1 AMS perfectly. If you can get it on sale, it’s a no-brainer—just save yourself the headache and use a magnetic driver from the start! ... show more

    • Good but needs a lift handle
Works better than expected, other than there is no grab handle on the ams dryer which makes it akward to open and close. The functionality of the dryer works good.

    • Sunlu ams heater
The heaters are perfect and work very well. The problem is that they are 110V and not 220V. Also, there is no mention of the type of power supply that they use. For people in the USA, they are perfect. If you live in Europe or, in my case, in South Africa, our power supply is 220V. It should be mentioned in the specs, so we know. I had to purchase a 220-to-110-volt transformer to use the heaters. ... show more
