Made with strong acrylic one gripe is the adjuster is a bit crude for height having just a bit of acrylic at the back which catches when adjusting but it's a minor issue! All in all well worth the money and it works perfectly so far!

Good value for money, highly recommended.

Funciona de maravilla.

Very good product, but the tubs would be flexible.

precio calidad buena

9a fait 6 semaines que j'utilise ce produit et j'en suis très satisfait, il n'est peut-être pas aussi efficace qu'un osmolateur, mais c'est un bon compromis

buen articulo que cumple perfectamente su funcion y facil de regular.

Have tested on several aquariums, so far there have been no problems even after 8 months, unit works just as expected.

One note - mounting bracket could be longer - it does not allow to be mounted on high sumps without making water level too high...

Itá good product, but it´s neccesary a minimun manteinance
