It seems like you’re looking for input on filament dryers. I did a detailed review of the Creality PI, which I found to be the “least-worst” dryer of the high-temp dryers I considered, all of them are deficient in some major design area:
At the time, pricing was a key factor in my decision to keep the Creality PI over the Sunlu S2, but even now, the testing methodology holds up and the purpose of the review was to allow others to weigh-in with their comparisons using similar criteria.
One major complaint I have with these dryers is that manufacturers prioritize aesthetics over functionality. Non-responsive touch panels and poor venting due to ‘pretty’ covers are common. I even had to fabricate a hinge stop to fix a clear design flaw in the Creality PI. Judging by other user comments, Creality clearly overlooked this.
While you’re mileage may vary, the choices of dryers that can operate at temps supporting PC, PETG and ABS are not widespread and many are overpriced in my view. By overpriced, I am of course using a price point of $55-$65 which is the average I’m seeing on Amazon for high temp driers.
