A manufacture can have a good warranty but if you have to pay $200 each way (400 dollars) and they won't send a CALL TAG, then what good is the warranty. Many companies will ask you to ship the whole machine back as they can't tell if it was the motor or the control panel or if just a belt broke. In the past people would send back a motor and find out the problem was not the motor and it delayed the problem 2 weeks longer. Also, most people a year later don't keep the original box so the manufacturer can charge you nearly 100 dollars to ship two over sized boxes to you (for the rail and base) and also charge you for 2 boxes.
They might tell you that they won't let you return it without the original box. So, this whole thing to just send back is gonna cost about 500 dollars. Just read the fine lines and really ask about the warranty before you buy. They rarely told me the fine details.
Restocking fee -
Make sure you know what their restocking fees are. Some companies don't charge a restocking fee but they are going to charge you for a new box and the original shipping to you. There are only a few companies that don't charge a restocking fee and send out a call tag if you don't like it.
Money back trial - Please make sure you get this in WRITTTTIINNGGGG. Every time I try to return something there is always some sort of problem. Maybe they have in the fine print that the machine must be in new condition. Oh, what about a scratch? What if I bought it at a discount and they want me to show my receipt that I bought from an authorized dealer. Nope. They won't let me return it since it was bought on Ebay. They are gonna make me buy a new box and pay for the shipping both ways. For some reason, this wasn't in the fine print. Oh, they just added this exclusion to the money back trial last week. How convenient.
Pleasure just make sure that you know what you are getting and get it in writing before you sign.
US Service Centers - This is something to know about if you get a machine that is known for breaking down easily or that is going to be used in a commercial setting. Most machines don't have service centers in the USA or Canada so in order to get the machine fixed you have to ship it back to Korea or China wherever its made. There are only a few brands that have service centers in the USA. The biggest ones are Zaaz Studios, Hypergravity, and Vibeplate. Zaaz has service reps in almost all 50 states or can bring it to a local Costco or Sams as they sell them.
Changing belts - This is the biggest problem with most machines I've reviewed after about 6 months on cheap machines. This problem with belt stretching with heavier people is a big problem with cheap machines that use these cheap belts that usually off gas a terrible smell when they get warm.
Common problem on shaky handrails: White Finger (google white finger, Raynauds and you can see what happens if you hold on too long to the hand hand rails on certain machines
This ONLY affects the fingers by the way. It happened to me at home and I tried to wash my hands. I thought I had paint on them. They kept on getting whiter the more I washed them. I went to the emergency room and by the time I got there my hands were back to normal. I must of looked like an idiot. They still charged me for an office visit.
Every finger was as white as liquid paper. From now on I will test each machine for white finger to see if they turn my hands white. These cheap machines resonate the frame so much they can cause this.
Warning: If Raynauld's phenomenon is repeatedly invoked it can cause permanent damage similar to the results of leprosy
I know nearly all the complaints on the most popular vibration machines. If there is a machine you are comparing and want to know if there are a lot of problem with that machine, let me know on my vibration questionnaire.
I can go over all the problems I experienced as well as the problems customers have emailed me about. Most complaints are from brands that I don't even sell. I am very aware of the main problems with most vibration machines.
