Yeah im not saying there all rubbish, the ones ive seen/dealt with that have the remote start etc have all been the cheapest of cheap ebay jobs that dont seem to last very long, ive had a couple that i have had in thats failed thats all, but as i say cheap universal tat, even the decent exspensive bike alarms naff up, ive removed more than ive fitted due to faults, but car alarms seem to be alot more reliable than bikes
you buy cheap get cheap there are tons of cheap china counter fit parts out there with no libality insurance. It is buyer be wear on the ebay shopping
