Yes, they are really nice folks who stand behind what they make, imo. The folks there are fantastic.
We ended up doing what I did with my own Silver uMax... as I also had a problem w few months after owning mine, the toggle switch must have gotten dirt in it, it no longer would allow me to switch between Disc and AM mode... so, I had called the folks in Prescott (I live in Phoenix) and asked if I drove up there, would they be able to fix it same day... they said they would try... so I drove up there, dropped it off in the morning, and kind of hung around Prescott for a while and they called, it was all set. So, for my friend, we did the same thing... called, drove down, etc... same outcome, great folks over there. Really appreciate the service, they did not have to do that.
Also, for you silver uMax owners, after my issue was resolved, I went and took the rubber top off an eye dropper, and it fix right over my toggle switch, almost perfectly. I used clear silicone and attached it.
Been probably over a year now, and it still works perfect... this rubber top keeps the dirt out of that switch. A mod worth doing.
And again, thank you to the folks at Tesoro, appreciate your customer service and a fantastic product. Please keep up the great work.
