Great price and works great. The only thing is that the temperature control switch needs to have a longer wire. No matter where I put it under the fireplace , it did not get hot enough to turn it on, so I just removed it as I have a fan switch on the wall. Not noisy at all.

Works great and is quiet. Easy to install and have to stand next to the fire place to hear it. Way better than what I did have

Works as well as similar fireplace fans, which all appear exactly the same, for one-third the price. The wiring came preassembled except for connections to the fan unit. The instructions are not very useful, however you can find video instructions on other product sites. The fan does displace more heat than the fireplace did on its own but is not extremely powerful. It’s also relatively quiet unless turned to the maximum speed setting. The fan wire length is sufficient to reach the back wall and the fan unit just fits under my Heatilator fireplace. Six key items to know when installing this fan: 1) Even though the wiring tag states that either wire can be connected to either fan terminal, it actually does matter and won’t work if reversed. Test it out to make sure it works before installing under the fireplace. 2) The magnetic temperature sensor should be installed upside-down underneath the fireplace (ideally near the bolt sticking out from the bottom but not critical). 3) The green grounding wire can be attached anywhere on the frame of the fan. I screwed it in underneath the plastic loop using the existing screw although I’m not sure why the loop is there. 4) Fan speed knob is attached to the black control unit using the small tightening screw. I assume the washer goes on first followed by the threaded nut but not sure. 5) Plug the fan into the Remote/Aux outlet under the fireplace since it is always-on rather than into the Fan outlet which is a switched outlet. 6) The fan unit should be installed against the far back wall of the fireplace with the fan air opening facing straight upwards.

Bought this and installed it myself, love that I can easily adjust the fan speed, the noise level is a bit louder than I’d like but the efficiency of circulating the heat makes it worth it! The fan noise is not distracting, no different than the furnace running really. It was the perfect size to squeeze in between the framing and the gas line for my fireplace. So easy to install a single woman can do it! Easy to wire and power up!

The motor was oriented in a different way that the original. The metal it's built with is thinner than the original. The little red bearing cap on the end is made from a less robust rubber than the original and while I didn't take it apart, I have my doubts about the "ball bearing" claims that are made. It did however install very easily, it blows hard and it really isn't much louder than the original - not sure where those claims are coming from in some of these reviews. It does the job for a fraction of what an original grade of this part would be and if it gets us by for a few years I'll be happy. Definitely does the job but don't expect USA-made quality.
