Naoza, you may be an exception rather than the rule. Razer Deathadder has common reviews of the same issue.
Their QC methods probably don’t include a click rating, ie. how many clicks before failure (under normal clicking pressure).
You would assume as a prominent gaming device manufacturer they would have both good design and good QC.
They do, to an extent. However it would seem that they’re cutting costs on components etc.
Maybe their tournament line of products are more reliable, I wouldn’t know.
