I've only used Rumblex 4D twice. It felt great those two times, but it's too early to see results or make a qualified assessment. I'll check back in later!
If you are wondering if you should buy this, the answer is YES!!! My only regret is not getting one sooner! I've used vibration plates in the past, and this is by the best! I love the different modes and speeds, the stability, and the work out straps are an awesome addition!!
I'm so excited to start this new journey! Just opened up my box. Ready to go! I will definitely be back to share progress! Being a 54 year old woman with some life challenges, this is the path I've chosen for fitness!
