I ordered a two-pack and liked them so much that I ordered another two-pack...and then a third two-pack. I dont guess you can endorse a product more than that. I now have one in my house, one in my garage, one in my car, one on my motorcycle, one in my wifes truck and one in my stepdaughters car. Now my mother-in-law wants one so I guess Ill be putting in another order.
