Excellent - nice glue side with 3M adhesive. The resistance of the heater is 192 Ohm, as expected.
Received ok and it works fine. Seller is absolutely reliable, I have ordered a pad with custom punched holes to fit the bed leveling screws posiions of my 3D printer (a Anycubic Mega Zero).
Installed under original bed of Anycubic Mega Zero. Temperature manually managed with a cheap SCR 220V AC dimmer (thermal probe not yet connected), because printer is still under warranty, so with less tan of US 15$ you can get a hot bed working with no manufacturer warranty avoiding.
