worked quite well till I tried petg on it
2/5
Worked great for pla, pla+ and tpu but my first attempt printing petg at 245c nozzle and 80c bed ruined it on the first print.
The petg stuck but it stuck to well, I event placed it in the freezer hoping it would release. trying to get the print off literally ripped the material.
Also you have to be very careful flexing this stuff as magnetic part cracks.
