I became dizzy the first time I stepped onto it. The the third time was much better. I am still learning what it can do. I am still working up the amount of time I can do on it.
I am just unboxing the Rumblex Plus as I type, but wanted to comment on the ordering process and receipt of the unit. Ordering was easy, tracking was provided and I actually watched the UPS driver set it down by my front door (not throw it). So far, so good. Fingers crossed everything works as intended.
