I got it for my old synthesizer Casio CZ101, and for the dimensions is almost perfect. The design is really well done, in fact
the structure of the bag is well sewed and the handles (that you can joint with Velcro) and the strap are in well balanced.
The strap is not fixed to the two extremes, but more close to the handles, so it is much comfortable to carry your instrument
Very useful also for other pieces of equipment
Would be very nice if they could add to it the possibility to carry it like a backpack!
