Just got yesterday a week ahead of when they said and I hook up today works looks great

Two RV -Bought TWO. One mounted in the living room. The fan is so loud I had to unplug it. The second was mounted in a 5th wheel Basement and it could still be heard in the living quarters. I WISH IT WHERE NOT SO for everything else including the price was great.

Great value

Returned

A lot of reviews mention how loud it is. Well, it is certainly louder than the original one. However, to replace the original one it would be at least double the price. We call that a push. Ease of install will vary depending on your rig. For mine I needed to get another piece of ground wire as the lug is in a different location the the original one. That said, if you think you will ever need to adjust the voltage be mindful on where those switches are when you install it. Otherwise, it works well.

Good item
