I'm using it with an Akai EWI Solo. The padded strap is very comfortable, the cord length adjustment works smoothly, and the adjustment range is a good fit for the EWI. The hook holds the EWI securely, unlike the open hook of the strap supplied by Akai. The only thing I don't like about the hook, is that the opening lever has very sharp corner, I might take some sandpaper to it.
