Just added one a few days ago so I can't say too much about it. The quality and 'feel' is pretty nice.
It installed & connected fine and seems to be working as advertised. Totally silent after running a little. (mechanical break-in) I can't hear it running at all unless my head is in the sump. The tank is in my living room.
The app is pretty easy to use and connects up fast and consistently. I only use the dosing part of it so can't comment on the other stuff. There was a little confusion with some of the terms they use in the instructions. Once you use it a little they start to make more sense. lol
The tubing/mounting kits for it are really nice. The tubing is nice and is silicone-like. The tubing mounting rail thingys are great and they give you double sided foam tape if you can't/don't want to use the screws. The bracket that mounts on the sump that holds the tubing ends is a little small though. I think it will fit up to 1/2" glass. I use a 20 long sump and I had to cut the inside lip of the plastic rim to get it over.
