VibroGym:

Hi Caz

there is a huge diferance between power-plate & VibroGym

VibroGym is the original machine formaly known as the power-plate some time ago the world distributor of the power-plate broke his contract with the manufactour & build a plastic copy made in china try the two machines power-plate next generation is like a toy compared to the VibroGym

Sounds a bit like sour grapes to me. I use Powerplate machines with PT and rehab clients within a gym and also at a weight loss clinic and have found them to be very good to use and have not had any quality issues at all.  Also used Galileo machines (used more in clinical/medical setting) but have not had an opportunity to use a VibroGym yet.  Would have doubts as to the build quality of some of the cheaper models of vibration trainers that are now available (under £2000) and also whether they are able to maintain a frequency above 18Hz whilst being used.  Not been able to find any detailed research on this yet though.
