The QPAD MK-80 is a well put together keyboard. It is perhaps not as durable as the simpler constructions available like the Zowie Celeritas. The Cherry key mechanisms are incredibly durable and since the LEDs are positioned outside the key mechanisms the Cherry keys are not weakened at all. The attachment mechanism for the wrist rest seems to handle abuse quite well.
The rubber coating on the keys is an unknown factor here. We have not come across it before and therefore we have no idea how long it will last. During our tests the surface held up really well and it is quite scratch resistant. Since the keyboard has clear keys painted black, the lettering will remain clear for a long time, until you wear through the thick black coating.
Since there are many things integrated into this particular keyboard the possibility of failure is a bit greater than that of a normal one. However, the MK-80 seems built really well. Two weeks of intense use did not affect the looks or performance of the keyboard, which bodes well for its long term durability.
