Product review (5 stars): Some modifications needed, but pretty good other than that
I finally saw what the other reviewers meant when they said that the connections were a bit different. This isn't that big of a problem because the baggie they send it in also includes a piece with two terminals (gold piece in the picture), you can just cut off the old one and, strip the wire and  crimp the new one in, and now you have an extra terminal you can connect the included jumper wire to, to complete the connection to the heating element. I also had to rotate it to make it fit, and find an extra screw to make it solid (previous thermostat only used one screw and was installed vertically, but I installed this new one horizontally, making use of both screw openings). This is actually a bit more solid than the way it was before.

My only complaint is that the terminal they included (gold piece) felt a bit soft and flimsy, like it was going to break while I was connecting everything together, but thankfully it didn't.

Aside from all that, the actual components have been working pretty good for a past few days, no problems thus far.
