Flat, sturdy and a good fit, but low temperature
3/5
90W is not a lot and this bed struggles to get over 85c and at 12V it heats up SLOW, usually 30 minutes from 10c to 85c and I had to tweak my thermal runaway settings to get it that high without failing. It's good for PLA, but would not be suitable for higher temp plastics. I'm planning to over volt it to get more power out of it for faster heating times and higher temperatures. A higher Wattage would be much better.
