Despite its price, this is an extremely useful small wonder for wind players. I own one for every of my clarinets; one for E-flat, one for B-flat and one for Bass clarinet.
Pros: The material is hypoallergenic, washes well, durable, protective.
Cons: Only the price. For this price you can find copies of it (same material, just without the logo) for a tenth of the price. That makes me realise the unnecessary high profit they make on a product that, cheaper, I would recommend to all clarinet/saxophone players from beginners to professionals.
