[Gulfcoast Robotics] 24V, 200W 3D Printer Heated Bed Silicone Heater with NTC3950 Thermistor.

This was exactly what i was looking for, it heats up the bed fast. its great, can't knock off any stars for it being exactly what it says it is and exactly what i was looking for

The heater size was a direct replacement for my Makergear M2 that I was modding to use 24V with. The integrated thermistor is really nice and came in handy when my original thermistor failed. The only downside at least with my M2 and this heater is, the blob of silicone that holds the thermistor in the center of the heater caused it to stick out far enough that my build plate required spacers. But, otherwise, I'd definitely buy more of these.

Heats my 220mm x 220mm Cast aluminum build plate to 110c in a reasonable time, without needing to run continuously. Build plate is 1/4” thick atp Aluminum tooling plate. MOSFET on my MKS board is nice and cool.I measured a 10°C ( approximate ) difference from the actual surface temperature To the thermistor reading but that’s inherent when you have an embedded thermistor in a silicone heater . This is not a flaw you just need to know about it. Seems to be nice quality. No problems there.

I purchased one of these about a month ago and have been using it heavily. It maintains a good temperature across the surface of the print bed and heats up rather quickly. I have had no issues with the unit so I am pleased.

Heats up fast!

Heats fast and even
