The o-ring seals could be a point of leakage for any canister. The hoses/extensions are another. Priming takes a few tries to get used to, especially with a basic canister filter.
Steve, I've got an XP3 on the way from DrsFosterSmith right now, too, so I'll let you know how my experience goes. I'll also make a point of opening it up and verifying if the o-rings are seated properly, and lubed if need be. O-rings are the source of all life's problems, from your filter to the Challenger.

I also plan to set mine up, at the very least initially, in some sort of plastic tank for exactly that reason. I heard that some canisters can be tricky to set up so they don't leak the first few times until you get used to it - though the XPs are supposed to be pretty easy. I worry about little accidents, too - their names are Sandy and Tasha, my cats, lol. Sandy is a bastard just for fun, so I fully expect him to be a problem child.
