Great size

Love the size of it (approximately same length as your average computer keyboard but with more keys than a 25-key controller). Just not a big fan of the microkeys as I used them over time... Maybe that's just me being spoiled about having full sized keys... xD

Very versatile

I bought this to use with bluetooth and an iPad but the lag is pretty bad. I still use it but if I also use a bluetooth headset it is almost impossibly laggy. Still, I do find this product useful.

Nice keys but the casing is a bit bulky.

Nice keys but the casing is a bit bulky. You're buying this keyboard because you have limited space and the case takes up a lot here. Also, the pitch & mod wheels have semi-circular covers on each side which can make grabbing them a bit harder. They also don't have as much travel as you would expect.

Nice!

It's tiny, but mighty! If desk space is a concern, this little controller will do you just fine.

not too big or too small, very good feel on the white notes but the black notes feel kind of cheap and plasticy

Vulnerable to broke

I could use that no more than 3 months. The day suddenly came. When I commuted to my university with this one and in the train, this broke. I think hit from passengers in the crowded train was the reason for that but I cried how weak this Keyboard was.

Useful to small places.

it's really good to have next to you keyboard for quick ideas. But the key feel REALLY light. And the are REALLY tiny. So, again, only for quick ideas.
