Perfect fit
This thermocouple was a perfect fit for the fireplace and the tube was longer than my old one. The result was an easier installation versus the short old thermocouple. I originally got the wrong one because there are two ignitor assemblies for my fireplace. So, may need to be careful about that.

Exact replacement
Installation can be difficult due to placement of the connection points. In my fireplace, the connections are hard to access without some disassembly. That ends up being the hard part, not the thermocouple itself

Did the trick
Our fireplace had started igniting slowly when we turned the electronic switch on, then the flame started going out after a fairly short time, and finally it stopped igniting altogether. Installing this thermocouple made our gas logs work like they did when they were first installed a number of years ago. Ease of installation will depend on your model of logs, and with ours it was difficult. However, that is not a function of the thermocouple. Ever since I got it installed our fireplace has worked great, with the flame igniting instantly every time and staying lit for several weeks now.
