My first one, when i un-did the nut for the remote wire the bolt dropped into the body of the capcell so i had to send it in. my second one worked GREAT! for 5 minutes. after 5 minutes i smelled burning but it looked fine so i left it in. (was wired correctly) after one day the outside of the casing started to bubble and burn and it started only working for short periods of time (2-3 seconds) and now it totally doesnt work. im NOT getting a third one. also the directions are really short and unhelpful. not enough info
