IK Multimedia iRig Keys 2 Pro

so if you are actually a musician performing concerts do not buy this controller. seriously. i should have listen to other reviews...
i'm just back from a dozen concerts and i am really disappointed. the worst thing, as other have pointed out, is the micro usb conncection (i know, shoul've known better). micro usb is already the worst type of conncection but they managed to make a really bad one. i have an arturia keystep which is also micro usb, but still much times better than this one.
this micro usb connection is so bad it will eventually stop working during a concert and you'll have to unplug it and plug it back again. really a pain in the a**.
a bandmate bought the same (we both use it with an mpc one) and it's the same story... this is really the biggest problem, but it's something that will make you hate this keyboard and regret you bought it.
also, keys feel a little cheap, velocity sensibility is not the best... but i was prepared for those things and they would have not affected so much my opinion on this product.
too bad because it has other nice things about it: it's the only 37 keys controller i know of with full sized keys and without a ton of pads and encoders which i didn't really need... it is also quite light and portable, so it's really a shame the connection is so shitty.
the only use i can imagine for this keyboard is as a studio controller with a ton of duct tape on the micro usb to try to make it work consistently.
