I also use the X3 system, and they were advertising a similar device, but for almost 3x as much. I received it today and out of the box it feels very solid, and has a nice design. It connected very easily and set up was a breeze. I started with a quick 5 min session to see what it feels like and it feels great. But the BEST thing about the WAVER so far is HOW QUIET IT IS! X3 users who use their vibration plate device have stated in the forums how loud that machine is. The WAVER, so far feels very solid, easy to use, quiet. I can't wait to REALLY get into using it. Great purchase!
