I'm seeing results that are quite a bit different than what the earlier reviewer found. Bed related equipment: - 600W 24V power supply. - MKS 30A mosfet - 14 gauge silicone wire - 12" mirror printing surface clipped onto the aluminum - No insulation At 19.5C ambient temperature the bed heating results are: 60C - 2:02 80C - 3:54 100C - 6:41 110C - 8:52 (that's as hot as I ever need but the bed could go hotter) It works great in my DBot build and I really have no complaints.

Running on 24V, this bed is working well for me. So far I only print PLA and PETG and its temperatures work well for that. It is quick enough to 60C, takes about 11 minutes to 80C, 16 to 90C, and then gets stuck at around 96\97C when I stopped after 34 minutes. This is with no insulation under or on top of the bed with 20C ambient. Probably quicker to heat if if you put foam on top while heating or insulated the bottom. I use Anycubic Ultrabase as a print surface on top of it. I was concerned with the bow it had, but clipping it to the nice thick Ultrabase worked well enough to flatten it out. It is a bugger to solder if you use heavy gauge wire like I did. Needed my heat gun to add some oomph.
