WASTE OF MONEY. When my iPhone 12 wouldn't start up, despite showing no signs of physical damage, Reiboot seemed like a good option. I spent the $50, ran the program and it didn't fix the problem. Reiboot won't refund my money on the grounds that this may be a logic board issue, which is a physical defect rather than a software defect, therefore they don't cover it.
I gave this product a fair shake and went through all the motions with customer service, but ultimately they're happy to take your money regardless of whether or not your problem gets solved.
