My friends and I bought 5 M7 remotes, and so far I’d give them a “meh” rating. Of the 5, one had 2 controller board issues, with the cart randomly shutting off and would not turn back on. Mine started doing crazy Ivan’s (see Hunt for Red October) by intermittently stopping, then going hard right after starting up again. It would also randomly shut off. It’s been sent back to MC, so we’ll see. When they work, they’re great.
