These are so convenient to help line up truck and trailer on first try all by yourself. Takes away the argument with your significant other when it comes to towing and hooking up trailers.

This system is so easy even my wife can do it . I use it for my boat trailer and my Camper works like a charm easy to see the big yellow balls very affordable and well worth the money

This is pretty neat. It’s easy to use and easy to install and it fit well. I like the magnets that are located on the bottom of each telescope. The only thing I would prefer to be changed is the sponges be colored black instead of yellow. The yellow gets dirty very quickly!
