(This review was collected as part of a promotion.) We have been using this for about a week now. And it is such a help, I didn’t think I needed. The set up was relatively easy, clear instructions and photos. It was a pretty easy install, but you do need the proper tools it lists. It uses 4 AA batteries which you need to get, but other than that it’s a game changer, I would definitely recommend it to all my family and friends! Thank you influencer for sending this out to me.
