Just that it will last longer if you drain it every time after use. I got one as well, but it seems to leak at the nozzle connection and I'm pretty sure it's the hose because I had the nozzle on another hose and it didn't leak.
I ordered online because I couldn't find in the store and sure enough, as soon as it came we went shopping and there were all over the place!
But I like it otherwise. Very easy to carry around and store.
