Eletric cut-out help

So which one guys, QTP or DMH? Does it really matter which one, or are they both the same as far as how long they last?

My friend runs the DMH; we just pulled it off this weekend as it's stuck closed. The motor tries to open it but can't. Not sure how reliable these things really are :(

I selected a 3 1/2" QTP on a custom cat-back. Due to it's small size. The DMH required more space then the QTP. Located just before the rear axle near the Left rear seat floor pan caviety. I have low ground clearance as well, and, QTP fit better. I have to check for loose fasteners on the QTP, and, be carefull not to over drive the electric motor. Also, a short exhaust kick-down helps to keep the hot gas off the motor and floor pan. So far, it is still working. It helps alot with flow. The DMH looks to be a good unit as well.

I have heard good and bad about both. The DMH does offer a nice warranty though.

Ive had the DMH for 3 years now. The only problem I had was my fault (bottomed out and ripped the motor off) and it was replaced through the warranty. It is a great product in my opinion.
