I recently sent my D21 back to Mcdermott for "free" service and a small warranty repair. The collar on the shaft had started to peel. Mcdermott said that it was due to "climate change". I'm still not sure what that means. I have owned this since new, over 20 years, and have stored it in a hard case in my home along with a 20 year old Schon and a 25 Year old Meucci. Both the Schon and Meucci look new and have never been refinished. The Mcdermott was refinished about 10 years ago by Mcdermott and a new shaft was put on which cost me around $300. I almost bought a new Mcdermott a few weeks ago but luckily I decided on a custom made Schon that should be in my hands by the end of the day. I'm basically just venting but has anyone heard of this excuse to deny a warranty claim? I take excellent care of everything I own and do not understand how I could have stored this cue any better. Any advice on how to handle this situation would be greatly appreciated. Thanks
