Bought this one for a Roland Go:Piano that I had as my 'toss-around' keys. It's by no means a luxury item, but at this price? It has done the job well, zippers are good, and I found the large external pocket very useful for pedal, power supply, cables and the like.
Couldn't get used to the Go;Piano, so i sold it recently, including the bag. Buyer's remark: "That's a decent bag!" She's right.
