Too early to provide much feedback about the product; just unpacked the wrapping and took off service door.  As noted in previous reviews, however, the screws holding the service door in place were incredibly challenging to remove. Finding the right angle for the screw heads at the bottom of each tunnel was highly problematic - left me wondering if a human hand had made the original insertion or a machine. Then I actually strained my wrist trying to provide the constant force nesessary to keep the head of the screwdriver against the screws heads to avoid stripping the screws.  Getting the screws back into the original very small holes behind the access panel in the wall of the hot tub, with no visual access to those holes, was also incredibly difficult.

Seemed a very primitive design to secure a basic access door on what appears to be (and hopefully is) a well designed hot tub. Why not insert a small female/male connection system with machine bolts?  Something simple and doable?
