Great upgrade for Gen1 AMSes
I chose these for my AMS Gen-1 instead of upgrading everything to Gen-2, and it turned out to be a very smart, cost-effective decision. Being able to dry filament while printing at the same time is a huge advantage—something the current AMS Gen-2 setup still doesn’t offer. Installation was incredibly quick and straightforward. Since using it, moisture issues are noticeably reduced, filament feeds smoothly, and performance has been excellent. I haven’t experienced any tangling at all, and the color output looks clean and vibrant. The overall size of the AMS remains the same, though the shape now has a slightly more squared, box-style appearance.

A needed item that Bambu forgot to add.
The media could not be loaded. One of the best investments I have made in a very long time. Living where the relative humidity can varry from 15% to 65% in the same week, the Sunlu ASM Heater and filament dryer has let me produce some of the best prints for the last 2 months That I have ever produced. The fit and quality of workmanship in the dryer is better than Bambu's default AMS lid. This dryer has removed one of the concerns to printing. With it able to reach 70°c it will also dry some of my engineering grade filaments as well. I can not recommend it enough.
