Product review (3 stars): Good.  not great, but good.
Ordered this as my stove's old thermostat reads much higher than true, and I would often get overheat warnings at modest temperatures (300+).  No instructions are included, understandable as it is intended for many models, but I think that at least something should be included.  Perhaps at least an explanation of how to disconnect the old thermostat's clip without breaking it.  I managed, but it would have been nice.  For my stove, replacement took about 15 minutes, some of that time spent trying to find the fastest way to complete the task, basically not removing anything more than required.  Installation required two differently sized sockets.  Once complete, what better way to test than to bake a cake?  I set the thermostat to 350 degrees, and once preheated my thermostat read 345.  A vast improvement, as my old stove thermostat would need to be set to 450 to read 350.  Making pizzas a few days later, to achieve 500F, I had to set to 510.

I'm very satisfied with the amount of improvement, as it saved me from buying a new stove, but I would have preferred if the new thermostat read completely true instead of 5-10 degrees shy.
