BCZAMD 3D Printer Heated Bed 300x300mm (12"x12") - 750W 120V Silicone Heating Mat with NTC 100K Thermistor for Creality Ender 3 Max - Perfect for ABS/PLA Printing & Warp-Free 3D Models

Have been running for almost 4 months, pretty much constantly. It was easy to install and keeps my 350x350mm bed warm and toasty. It came with 3M adhesive, holds it in place very nicely. I did add insulation under it to focus the heat upwards. The bed is a nice even temperature everywhere, no hot spots. I would buy again in a heart beat.For those of you who read the one star reviews, please disregard. This heater does not have holes in it nor is meant to. Who buys a 110v silicone mat heater and blindly punches holes in it? I'm surprised natural selection hasn't taken care of those people by now.
