As someone on a tight budget I was a little hesitant in ordering a bag to accompany the Cajon I was buying. It was only recent struggles with plastic bags etc and the competitive price that made me look twice. I am so glad that I did! The case is good quality ~ the zips run cleanly and the straps are easily adjustable. Not a lot of padding so if you are looking to go seriously off-road the case would be of limited use but for daily handling it is ideal.
I took it out to do some busking and was amazed at how light the whole thing was ~ here the adjustable straps came into their own. I was able to walk freely and pretty unencumbered for about half an hour to my destination. (The bag was also useful to store my coat and such while I played!)
I've given it four stars instead of five as I imagine it is possible to buy bags with a little more padding but, as I say, you probably won't need it if you are reasonably careful anyway. A good accessory!
