We bought this Klin Sleeve to work grips and bite stamina as well as for distraction and quick reward for our club dogs.
It's a well built unit and should last us many years. We used the cotton cover not the jute cover. It was easy to put on the sale ve and the dogs enjoy working with it.
The sizing of the sleeve itself is a little on the small side. The 2 people using it are on the tall side 190cm so the elbow crook is a bit uncomfortable and the shoulder cap comes up a little short. The sleeve is sized for someone more in the 170-175cm range for fit. But for what we use the sleeve for it does the job.
