My Tech Fun | They fixed it: GratKit Firefly filament dryer (re-review) @MyTechFun | Uploaded December 2023 | Updated October 2024, 11 hours ago.
Few month ago I tested GratKit Firefly filament dryer and my main problem was that it couldn't heat up the air to set 70°C. GratKit fixed the problem in mass production and they sent me new product for the testing. According to my measurings, the reach the peak of approx 75°C in 20 minutes.
