I got mine when I got my bass from him a year and a half ago. I used mine a lot in the city in the rain and snow, so it was pretty abused. However, I started to have problems with the velcro on my case that it attached to. Then I had problems with the wheels wearing out, but that was a more recent issue. So, I guess you can make your own judgements as to whether it's worth it or not. Hope this is helpful.
