## Customer Reviews

### ⭐⭐⭐⭐⭐ Really packs a punch
*by P***K on March 12, 2018*

This thing is insane, I'm convinced it could boil a pot of water faster than my stove if I wanted. Heated the bed of my FT5 to 100C in 3 mins and holds temperature very well in pwm mode with the recommended SSR. When autotuning the PID controller my controller threw a warning that my heater was overpowered and calculated a max peak temp of over 350 deg C was possible. Installation was easy, the pad came with 3M adhesive applied so all I needed was a clean bed to stick it to. I used my old 12v bed heater cables as an input to the SSR and then sacrificed an old power cord and wired it into the load side. It just needs to be in the 120v circuit, same as a switch and polarity doesn't matter with that. I'll definitely recommend this for an upgrade to any large printer

### ⭐⭐⭐⭐⭐ a very good product from a nice seller.
*by E***F on October 23, 2021*

i am happy using it in my 3d printer, works very fast and the seller send it in time, even with a pretty ornament additional. I am happy and satisfied, looking forward to buy againfrom them if i build another 3d printer.

### ⭐⭐⭐⭐⭐ It works
*by A***R on December 10, 2016*

The item arrived 5 days before the estimated delivery time. I have just mounted it with the basalt table. I have tested one time with a solid state relay controlling the input voltage and manual control of the relay. I do not have it working controlled with a rumba control board but the heat rise was at a satisfactory rate. This will be used with a mpcnc project and either the diamond 3 filament nozzle or a clone e3d single nozzle. This is an ongoing project which I work 0n as time permits so I expect that it will be some time before everything is working.
