I know it's been a while since the last post to this thread, but I thought I should share my experience with 41.22 in case anyone else is considering their Drop-In Kill Switch. I ordered it after seeing good YouTube reviews. I never got an email confirmation, so after a week I tried to email them for a an ETA or tracking number. I found they don't publish an email anywhere, you have to send an inquiry through the help section on their web site. It's one of those comment box deals.
After another week of no response, I sent another inquiry, this time to the sales inquiry box instead of the customer service. After another week, I finally got an email stating that my order was now complete - no explanation if that meant it was ready to ship or if they thought it was delivered....? I replied saying that it's not complete until I've received it and that I hadn't. I searched the web, finally went to the BBB and found their parent company (same address), who at least had a phone number. They didn't answer, of course, and never returned my voice mail. I was just about to call the BBB to see what I could do when the package finally arrived. I did notice what I hadn't before - both 44.22 and the parent company have 'F' ratings with the BBB.
I had the flu, so a couple weeks went buy until I went to install the switch, only to find that the relay they sent would not fit my 2018 1500 by a long shot. Our starter relays have four small parallel terminals, one at each corner. Their relay has much larger terminals at right angles to each other. My truck, model, engine size, etc. was all spelled out on the order, and on the packing slip.
I again did an inquiry through their web site and left a voice mail at the parent company. So far, no response after two full business days. I don't expect a response, but I guess I COULD be surprised (doubt it). I think my only recourse is going to be filing a charge dispute through my bank.
I'll update this when there is a resolution. BUYER BEWARE!!!
