While this simple piece of metal functions perfectly, there were two problems. a) I expected to receive 2 of them because the photo shows 2 of them. But the photo shows 2 in order to display both the front and back of the device. I think this is misleading. b) I was charged a $1.50 battery fee because I live in Florida. But this device is not a battery. It's a small piece of metal that fits over a battery terminal. It does not replace an existing battery, thus there is no need for a battery to be recycled. I think the small fee was charged in error and should be refunded. Imagine my disappointment when I realized I would have to buy another and pay shipping and the incorrect battery fee! Instead, I bought from a Tractor Supply competitor at a local store.
