I bought two of these to mount two different switches for my kids and quickly found that it takes VERY high precision to twist the switch into the charging port. It only took a few attempts for the charging connector to enter the docking station. I disassembled the docking station, it is simply two molded plastic parts, a cable and a charging port. The problem is that the charging port is on two small pins that sit on U-shaped supports in the case, but aren't as wide as the case, so they can slip off their mount. I put it back on the U-shaped supports and reassembled it, but the next time I tried to dock it failed immediately. Another dock (different color) seems to have the same problem, but we were more careful with it and it didn't happen.
