We have a Tekonsha break controller on our 1999 Chevy Silverado 1500, but not the Prodogey which has a digital read-out. We have a cheaper model with a dial/slide switch. It's had so much use between our trailer and boat, and the fact that my husband is a mechanic and truck driver and has to mess with everything all the time--the name's rubbed off and you can't even read it anymore! It never fails and is easy to use.

At Camping World the Prodogey lists for about $159, but if you become a member it's $129, which basically pays for your membership. The non-digital runs about $70.
As in earlier posts, consider placement and being able to reach it when the seatbelt is on, and practice so that you can instinctively use it should the need arise--heaven forbid...but it can save your life, literally!
Happy trails!
