This listing is for a pair of gate openers. These gate openers are typically around $37 each and this listing is for a pair at $76. I ordered two of these pairs and paid well over $150.
I received only two gate openers. Not two pairs.
It has been five days since I notified the seller, which I did immediately upon opening the package, and have heard nothing. So all I can assume at this point is that it was an intentional rip off and they got me for double the price.
Buyer, beware!
