shaved door kit relay problems

I bought a shaved handle kit from protocol. the kit seems ok except for the relays. it came with 3 keep it clean brand 30/40 amp single pull double throw relays with heavy duty design and 2x retention whatever the hell that is. but they are junk I have already burned all 3 up. they stick bad and melted one of the harness's. so what is a good brand to replace them with. these have a lifetime warrenty but I dont even want to mess with them.

we just had the same problem with that kit
