The Doug's electric cutout on my truck failed due to high heat, thankfully in the closed position. I read this thread, figured why not give DMH a shot; everywhere I looked they were recommended. I fill out and order, and go to pay for it, but for some reason when I went to click on their "pay with Paypal" button, it would not load. So I sent them an email to see what I needed to do. This was on 6/2.
6/5 rolls around, still no response, so I gave up on them and placed an order in to Raceready. The package arrived at my doorstep in 3 days. It's now 6/13, still no response from DMH. If they treat new customers like this, I don't want to know what hoops I would have to jump through for a warranty claim.
This is my experience with both companies, figured I should let you guys know.
