I have 3 of em now but what shall I say....
First, sure these are the best looking reservoirs I've ever seen.
Maybe I just had bad luck but all 3 leaked: #1 at the screws of the helix, 2# at the tube of the uv one and the 3#...well I mounted my BP barbs (with my hand) and the bottom plate just popped off and I'm not Hulk Hogan ^^
Well fixed all with 2 components epoxy glue and no leaks anymore...but was rly a bit sad
