All user reviews of 2/5 for the Contest STB 520

I use these machines club since September 2012.
This is a fairly popular machine that has a lot of people, and apparently in quite satisfied, however, for my use it is not a very competitive product with its quality.
Who says use club, said use "intensive", not in the sense of Strober permanently, but in the sense that the machine is turned on several days each week, and a malgrès not really intensive use, showing signs of weakness After a few months after buying new.
The features are not bad in themselves, two-channel intensity, speed and armor function. Only, or that there is sin in the design and manufacturing quality.
This is the Chinese component neither more nor less, feeding problems, strobe which freaks, of really poor quality original xenon tubes ... already three failures on 3 machines in less than a year ... It is puzzling. Meanwhile in another club, I own FL1800D Geni (also sold under many other brands, JB Systems, Dune, MacMah etc.), which certainly does not function blinder but turn smoothly for 3 years and yet are more stressed than the STB 520.
Brightness level, it is still below the FL1800 is average.
Very very blah as a machine, it is better for a similar price. Note 3 to the poor quality of components and assembly compared to other strobs same quality.
