It's a little early being asked for a review when you first open and register the item. All I can say it is seems much more substantial than the one I purchased before and that it came timely and packaged well.
I just received my Rumblex 4D 2 days ago and am loving it so far. The unit is very well constructed and the manual is very well written, making the setup and explanation of all the modes very easy to understand. I have been doing 2 sessions a day so far and have tried it on carpet and on hardwood with the included mat. I couldn’t believe just how quiet the machine was! Very impressed with the Rumblex 4D so far!
I’m excited to experience the benefits of using the Rumblex plus. The battery was a little finicky to get back in after taking off the plastic piece and when I flipped the machine on it’s side to install the screws, one of the silver decorative plates fell off, so hoping there are no other issues!
