I love having a wireless pedal on my dynasty. I never realized how much better it would be until I bought one. If mine dies, I'll be buying another one.
I've had one since they first came out about 5 years ago and have never had a problem with it.
Like Griff said, if it died tomorrow I'd get a new one right away.
$650 is almost $200 cheaper than what I paid 5 years ago.
Glad to hear you like it as well as the rest of us. I enjoyed using mine today for several hours. I was going back and forth around my welding table the whole time. I had slid it around on the floor so much I managed to unscrew one of the feet. No problem to just screw it back on. I was kinda surprised when I stepped on it and it wobbled all around.
