You get what you pay for. Always the case. Buttons may look the same, but the switches could be different etc. Granted I am still learning, I see definite pros and cons in crertain products. The legit Happ Buttons I have and the Chinese generics are about 90% equal. The happs have a little more fit and finish IMO, but could be totally psychological. Pay attention to the microswitches used, thats the thing that makes it all work. If its crap, the plastic component wont make up for the shortcoming electronically. YMMY.
