I can see why it's so popular -- light, beautiful design, goes with Apple stuff

At the same time, the unboxing of the Xkey 37 was a satisfying experience, and the solid build quality and sleek design certainly help to justify the price point.

I needed a small, quick to setup, convenient controller to hook up to my MBP for sketching ideas

It's a pretty awesome midi controller

Great concept this controller is great for anybody that needs space, it's very compact

Look: this keyboard looks like it was made by Apple, it's stylish, and well built

While this is obviously a device that is well-built and appealed to me, I'm struck by how weird the overall concept of it is.

The pitch bend works surprisingly well and it is sensitive enough that you can easily control what interval you bend to (not just full on or off)

Great key response.

The keys are full-sized, have a small difference in height between the black and white keys, and have great response

Very nice machine arrived properly thank you ..

Love the thinness and sleek look of it.

I'll get into my gripes (not really any) about the keyboard further down, but for the cost, this has been a fantastic purchase, and I can totally recommend the Xkey 37!Xkey 37 vs Xkey 25Initially, I was going to purchase the 25 key model, but to do the type of music that I like (piano accompaniment), the 37 key model was much more useful.

I believe the 25-key version, however, still sells for $99, so that is a pretty significant price jump for adding a single octave of keys, though the Xkey 37 has a few connectivity advantages over the Xkey 25, which I will discuss below.(UPDATE 02/26/2016 - About a week into using the device, I'm going to stick with the 4-star rating for the foreseeable future.

Great concept, but not at all like a real piano

I was really disappointed that this didn't work better, as it is a great concept.
