If a blinded subject is asked to evaluate VT007 vs. GH Accelerator without being informed of the price, I am sure the subject most likely would think VT007 is a more expensive model. VT007 is far more quiet, has adjustable frequency and amplitude, has a remote control. GH Accelerator has a fixed freqency, no amplitude switch.
Sometimes I still like to use GH Accelerator. It is designed to use with X3 bar. I do like the convenience of not needing to change the frequency. Second, GH Accelerator is smaller than VT007.
My X3 bar belt encircles GH, so after the exercise, I can simply put down the bar on the floor. With VT007, the belt does not encircle the unit. If I just put down the bar, it will lean on one side of the unit. Since I do not want a 40+ lbs object constantly leaning on one side of the unit, I need to move the bar away from the unit after each use. So I am keeping GH Accelerator as a dedicated unit for X3 bar training.
GH Accelerator does not come with a remote control. You turn on the machine by stepping onto the plate, and you turn it off by hopping off the plate. The main problem is that as I hop off GH Accelerator, it makes a very loud noise when the plate is still vibrating without any weight on it.
In order to solve this problem, I always need to have the control box (which is similar to that of VT007) within my hand's reach, and turn off the switch before I hop off the plate.
VT007 does not have this problem. You could choose to use the control box, or you can use the remote control, to turn on and off the machine.
Also, since the base plate on GH Accelerator is removable, it certainly makes rattling noise as I move my foot positions, or as I step on it, which does not happen with VT007.
VT007 is definitely superior to GH Accelerator in terms of the quietness of the operation. Price-wise, $400 vs $1600.
