First of all, there are no private labels who have original manufactured parts for their machines because it's not really even theirs to begin with. So, all these companies are now offering 5 year, 10 year, and a few even lifetime warranties. How does a young new importing company offer a lifetime warranty when they haven't even been in business long? How does the "vibration machine brand" company owner offer a full lifetime warranty if the factory in China only gives 1 year.
The easiest way I've found out, for example, in the electronic industry, is if you've been scammed is to see if the company's brand on the control panel matches their brand on their serial plate.
Some very sneaky companies know this and will have this covered but once you know how to uncover the truth of who they are importing from you can understand why they did it. YOUR WARRANTY IS NOT REAL WHEN YOUR VIBRATION MACHINE HAS PROBLEMS!!! Do you really think they really care about you after you buy? They just want your money. When you need help, good luck not paying their full price to replace the a broken part.
BETTER YET, why should you want a replacement part if the first one didn't work? Just look for a legitimate company if in the long run you don't want to worry about your machine. It doesn't matter which brand. 99.999% of these brands all claim they have exclusitivity but when you research deeper you find out they are the samd but with different logos on them. What is funny is they have different specs and information on them when they are the same. When you ask them which one is better they tell you that their machine is better. HOW IS THIS POSSIBLE IF THEY ARE EXACTLY THE SAME MACHINE!!! When I catch them in this lie so many other of their lies are exposed. I won't recommend them when they do this. It is really hard in this industry because some of the best machines are rebranded and most of these import companies are playing this game.
