Understanding Quality vs Price

Pivotal Machines

The basic function of all pivotal units will be the same. As the sole job of the unit is to tilt you from side to side trying to get you to re-balance - over and over again until you get tired. They will differ in how far they will tilt you, and argue how fast they should tilt you. However not much force is required for this action as it is not trying to lift up your entire body weight. The job can be done with one cheap motor. And no - this mechanism has no patent on it that would stop anyone from building a similar unit.

In other words a cheaply built machine can feasibly give you the same workout as the most expensive model. I use the word “feasibly” due to the following limitations of cheap machines:

  1. The bearings will wear out quickly.
  2. Only limited body weight can be taken.
  3. If the upper speeds are used, it will wear out even faster.
  4. There may be a limited amount of usage before it breaks down. (I know they come with a warranty, but they are praying you get bored long before that happens).
  5. It will drop speed if you are not standing perfectly in the middle of the plate.
  6. The cheap home units I have seen are very unstable with a lot of movement going on that is not accounted for in any of the studies I have read.

In summary, the cheaper Pivotal units can be used by light people, who are not going to use it much, and don’t mind being thrown around randomly.

Note: Follow the programs given with these units at your own risk. Remember the word is LOW. Low cost, low function, low education, zero responsibility. One operator was denied warranty work due to the fact his customers
were “Too heavy and going too fast” so the rip-offs do happen.

Quality units will not have the above limitations and should perform to their exact function for a number of years. This is a must if you wish to operate a unit in a business.

Lineal

Now this is completely different. Unlike Pivotal units you cannot build a cheap Lineal machine that also performs its basic function. Unless of course you are one of those marketeers that like to say “Vibration = Vibration Training” (which it not true).

The machine has to be able to lift you up and let you drop back down at a rapid pace as though you were doing mini-jumps. If it loses speed or pressure in any way you just end up with a massage for your feet.

Here is a good field test:

Jump up in the air just a few inches landing with your legs bent. Feel the pressure and movement your legs go through when you land. If the machine you are looking at feels less than that then it is not a “Training” machine.

Note: Vibration Therapy benefits may be obtained from “lighter” feeling units and weight loss MIGHT occur due to increased movement for a short time frame after you start, so if this is all you are looking for you do not need to spend a fortune.

Be aware that weight restrictions and other mechanical problems may occur with the usage of cheaper materials.
