Their lifetime warranty is a rip off. you have to pay for the replacement and shippings fee which equal to buying a new kit. They say one thing and charge you and arm and a leg on the final replacement order. recieved the upgrade kit but did not work correctly. email them the problem. they told me to return the item for even exchange new kit. had to pay for the return shipping. they email back that i've to pay extra for the new replacement. decide to cancel order and they said ok but charge me a restocking fee which the email said waived. that really BS! Was told don't believe everything on the internet till i had the bad experience with them.
