Unfortunately I have to give a bad review. On December 9th I ordered the wireless tire pump I did not receive it until December 30th, I emailed statik numerous times looking for a tracking number no response. It got to the point where I had to get PayPal involved, I finally received my order only to find out it did not work. Email statik again with no response got PayPal involved and walla I finally received a response. With in two weeks I received a new pump, I haven't used it yet so no update. There probably a good company but they need to respond to their customers a lot faster. So at the end of everything it took almost two months to receive my order. Thanks John
