Fit like a glove. Easy install. Works much better than the old one.

Worked well, fit right in! Now vibrates and makes excessive noise.

This replacement bath fan/light is as described, and the installation went as smoothly as others have described. The only cavaet I would add is that attaching the metal light assembly/white fixture cover is the last step before screwing in the bulb, and the provided vertical threaded bolt was too short to affix the wing nut, so I took down the unit, and swapped out the original (which was much longer and provided ample length).

We needed to replace a super old fan in our 20 year old home but couldn’t find the replacement anywhere, until we found this one. Easy to install, sounds great. It’s been a few months and it still works perfect

Since the fan in my bathroom light quit, I was considering replacing the whole thing. While researching, I discovered that there are not many fan/light combos made today that are going to fit in the hole in my bathroom ceiling. Then I found this. It is cheaper than a complete replacement and is all I needed. Once you get the cover off and the light bulb out, it's just one wingnut to get the light fixture out. Then one screw to get the fan out. I put the new one in, plugged everything back in and closed it up again. Works great and it is pretty quiet.

Perfect fit. Exact replacement of whole unit $143.00 this took 10 minutes to install, no tools needed. Fan works perfectly. If the model listed, definitely buy this and save some bucks. Not everything needs to be replaced, FIX IT.

This is a nice fan. It is actually quieter than the original. It is easy to install, but here is one tip:The vertical screw attached to the fan housing, which holds the reflector and socket in place, is shorter than the original, so you may have to take the one from the original and swap it out. In order to do this, you have to remove the motor- but that is easy too, as only two small nuts hold it in place. Remove the motor from the new unit, replace the vertical screw with the longer old one, and reattach the motor with the two small nuts. That's it. Just added 5 to 10 minutes to the install process. No big deal.
