First hand.
The whole assembly is very cheaply built.
Fell for the $35 "trap".
Could not get money back either because the "vendor" claimed that the unit had been used already.
Well, from my view of the universe, its hard to see if a piece of equipment leaks unless you use water. (??!!)
From what I understand I am not alone. Many other have complained about problems with this unit.Please stay away. The price makes it very very tempting. I know !
Stick with the more well known brands. I use a Tetra UV-2 and a Turbo Twist 6x now. Very happy with both. The Tetra quartz glass assembly has leaked on me once in four years and I had to replace it ($53 !), but the turbo twist 6x seems like the winner. Nice assembly, and no leaks so far.
I hear that the Jebo 828 canister filter is not bad. No personnal experience on that though. I am strictly an Eheim fan (2x2026 , 2227, 2128 )
