Has anyone used a HydraPak Reversible II Sideseal Reservoir ? If so, are they any good?

 I am tempted to buy one of these due to the  "Plug-N-Play" valve connector which according to the manufacturer allows you to remove the tube and the fact that the bladder is reversible for cleaning. 

 I currently have a source widepak which has now got black stains in the tubing and I am finding it impossible to remove the tubing from the rest of the bladder to clean it.

Should I risk buying one of these or stick to the more commmon camelbak?
