Document: This product has been a lifesaver not only for my mom but me as well. I originally bought it for my mom because at work she is always on the move and stresses out. Each night she comes home to use this and she loves it. It gets rid of her aches and pains and she knocks out after. I tried it out for myself and let me just say that it is a massager and workout machine in one. The second I got on, I was amazed with how much it could do.
This machine is great, I would recommend it to anyone. If you haven't tried this machine you need to. LOVE IT!
It has reduced my dents and cellulite a little. It does somewhat it says what it does but the disappointment is that its not a crazy fit. It comes with stickers to put on that is another name than crazy fit massager. It looks exactly as the picture except for name. The screws get loose and I have to tighten many times and it makes a lot of noise. It feels loose. Doesn't feel like the vibration I get in my doctors office, something is off. But I do try to use twice a day when I feel my neighbors are not home.
just received it yesterday, husband put it together in a half hour, used it today and I love love love it! I've used this model before and this is not a knock off. does anyone know what position to stand in to work the back of the legs? It has an incline, maybe I should use that? the seller was also really wonderful and answered every question I had. I had ordered another model and sent it back the same day so I wanted to be sure that this one was the one I was familiar with.
Good - My wife likes it. It is quiet and appears to work just fine.Bad - Our bedrooms all have arc-fault circuit breakers and the machine trips them when it is turned on. We have to plug the machine into a plug located in an adjacent bathroom.Ugly - The owner's manual. What a poorly written piece of junk paper. If you followed the few installation instructions you would put it together incorrectly. Poor English, terrible grammar, and it just doesn't make sense. The unit comes with a 4" wrench and a 4" screw driver; both are inadequate to properly tighten the screws and bolts.
The first time I was on it 10 minutes on low setting it felt great and I thought wow easy to do this. A little later I did the P1 program which runs 10 minutes and rev's up. OMG the higher settings are pretty intense and I truly feel like I had a workout. My thighs were burning like I had done a lot more work than just standing on a machine. I actually slept pretty good that night too. Today I tried a few of the exercises like sitting on the machine, inner thigh stretches, doing a plank, etc.
We have been using this for several months now and recommend it to anyone with a stiff back or joints.
Nice unit. Has some challenges with putting it together, but if you partially tighten first, then, go back and fully secure them, it works fine.Good quality and shipping/packing.I would recommend this item to anyone.
I wanted a vibration exerciser and tried one in a local health store. This works great, and it was $2000.00 less than the one the store was selling. I'm far from young, but i see my strength improving and I've lost four pounds so far.
This 2010 crazy fit massager full body vibration excercise machine has really solved a lot of my health issues. It is an indeed indeed five star.......for any health issues for anyone, who believes in improving health.SZ
