Review on CARMOCAR Shaved Handle Door Popper Kit - 2 Door Kit With Remote & ONE SET (85 lb) by Jair Baltrusch

The solenoids appear to be very solid and work well. I can't think of a latch they couldn't pull hard enough. They often pop when activated, so make sure your cable isn't too short or you'll bend or break the locking lever. Spring-loaded latches seem cheap, but are strong enough to open heavy firebird doors about an inch when the latch is released. I put them on the back of the door just below the latch. Some say that programming remote controls is difficult. I connected everything and tried the remotes before going through the programming process. They were both already programmed into the receiver so I didn't have to program them.
