I have a KWIK PYPT, my brother has towtector. They both have worked great in protecting out boats. I bought a new 620 in 2009. Tournament fish all over the place and other than a couple very small rock chips in trailer (almost not noticable) there’s not a ding. Noit 1 anywhere in glass.
I do agree with Wade, should be cheaper, but shouldn’t everything!!!
Make sure what ever you go with that it’s long enough.
Nothings going to 100% guarentee though.
