Review on SUNTECH SM 88 7500 Direct Drive Screwdriver by Carl Movahed

I bought this to turn screws while repairing mooring lines. It even worked great underwater. It's not a punch, so you have to keep the pressure up. Even with my little 6 gallon pancake compressor, he turned five 3 1/2" #10 wood screws before having to wait for the compressor to recharge. Put some tool lube and ran it a few times.
