After a lot of research looking for a replacement case for my alto sax, I finally decided to go for the Protec PB-304CT. The red version was tempting, but I decided to go for the more sober black version. Quality is absolutely first rate - stitching and material give confidence that this is a case that will last.
Internally, the sax, neck and mouthpiece have their own dedicated space. Two generous pockets on the outside provide room for a good number of accessories, and the optional backpack strap is a worthwhile addition.
The only minor issue is that the case tends to topple when the sax is removed. If the neck or mouthpiece are not secured, they could be launched into the air with the potential for damage. Overall though, a buy I'm very happy with.
