## Customer Reviews

### ⭐⭐⭐⭐⭐ Inkbird SSR combination with HEATSINK
*by J***H on March 18, 2024*

The Inkbird HEATSINK combined with the SSR worked well with my temperature controller. The 4 photos indicate an application of controlling temperature with an Inkbird SSR and PID control unit. Basically the unit maintains a set temperature to seedling's on top of a heating mat.

### ⭐⭐⭐⭐⭐ Worked for Creality CR10 S5 AC heated bed
*by B***T on July 20, 2021*

I mounted this on the upper side of my CR10 S5's PSU for my upgraded bed heater. I upgraded the fans in the control box and added a stand that has a raspberry pi and 12v Noctua fan powered by the Pi's USB. The exhaust from the case is never warm and I never notice a spike in my Pi's temps in octoprint.I was weary of fakes, which seem to be everywhere, but this one has worked great for me.

### ⭐⭐⭐⭐⭐ Do you need ssr-Da, or do you need a ssr-AA?
*by R***R on November 2, 2019*

Performed so well, I've ordered 2 set's over the last 8 months. Couldn't imagine using anything else. Definitely worth the money!One big call out is. You may want to research the difference between a ssr-Da and a ssr-AA and finally a low voltage contactor for your application needs. I only say this because it appears from the reviews, that many people are miss matching their ssr to their applications.I know that I did this in the beginning and toasted a few myself... Do the research first, it'll pay off in the long run.
