The flat surface is great… being asked to review while I submit warranty so haven’t used it a ton yet but my ankles have been hurting and I’m grateful it is flat.
I’ve had a rumblex plus for almost a year, my other one began having issues and error codes. They were quick to send me a new machine to replace the old one. Process was quick and easy and it’s nice that they stand behind their product and warranty. I can’t wait to get back to using my plate daily.
