Saves a lot of marital distress when hooking up trailers! I bought one from Harbor Freight the second they were in stock 10 years ago.

My wife has to be the worst *ground guide* in the world.
Could never figure what the hell she was trying to signal while I was backing up.
Always had to get out of the truck and see the position myself.
When an inch counts, she had me at least a foot off :)
