The product did not work. I am going to have to return it.

I bought this for my 2011 Forest River Forester 2301. After determining where all the connections were in my RV, not an easy feat as I had to remove the corner mattress to get underneath, the unit itself was easy to hook up and has worked beautifully since its installation.

You can’t give a credible review with only a few days in possession. I have it connected and its works.

Although it was a different brand than original, it was a perfect power match. The size is the exact same and build as well. I had it installed in 15 minutes and the fact that they give you a 4mm t-handle allen wrench was a welcome surprise. I'm not sure why others have said that the fan is too loud. It's no louder than the one I removed. Mine mounts under the fridge in a covered area so I never hear it operate. I appreciate other companies providing quality alternatives to otherwise expensive replacement parts for a good price. I feel like this was actually a good deal and would recommend it to anyone needing such a product. Thank you!

Unit is easily installed and works great. However, the fan kicks on every minute or when lights are turned on. The fan can be heard (very well) throughout a 42’ Heritage Glen fifth wheel. I returned the unit, opting to try another brand before remounting to an outside compartment.
