@osterizer and ea01bg: all that you say is very true and I fully agree with you.
A gyro is a part where i wouldn´t want to buy a cheap one.

But, you have to know that not everybody is able or willing to spend 100€+ in a part.
So people, like me, find themselves looking into cheaper parts.
If alot of people are saying that those parts are good or enough for their skill, than why not?
These cheap brands have a certain market, for persons like me, if they have good reviews, than its more than enough.

ONCE AGAIN: If I had the money, I would buy a more known/better gyro.
