Product review (1 stars): buyer beware
I ordered this product and tried endlessly to get it to work. I have installed many over the years, so its not like I don't know how...
But to my dismay I believe it is faulty, much to my surprise I tried too long and found that when I went to return it it had passed the date to do so.
I caution anyone too be swift in your return process so this doesn't happen to you.
