I got my P150 case about August 2006. When I looked inside about Dec. 2006 all 6 rubber bands were broke and my 3 HDs all fell.
I wrote to Antec service thru their web site and never got any reply at all. I did not persue it further because I do not trust any replacement of the same thing, and I like being able to fit 4 hard drives instead of just 3.
Clearly a defective design, and if Antec is not more aggressive about notifying people, they may become liable, regardless of written disclaimers, especially in states like California with an implied warranty of merchantbility, that supercedes a companies disclaimer. Of course you would have to have hard drive or data damage.
Antec has replacement bands that are quite different than the original. I suggest you call if possible and get the replacements. If you are outside the USA, send them another e-mail to support and explain the situation.
