Awesome value!
Top quality build and performance for budget price. Unbeatable value, best skimmer I've ever owned. Highly recommended.
Very impressed by the built quality.
Acrylic is very thick. Nice looking, nice performances and not overated like some other brands.

First I was very pleased of the bluilt quality.
. The acrylic is very thick. Very good finish.
The perfomances are very good and the pump is very quiet.
For the price it is probably one of the best skimmer you can find.
No regrets!
Excellent skimmer!

Excellent for the price
Super Skimmer for an unbeatable price. Absolutely quiet, great foaming. Very good workmanship and very fast delivery.

Normaly I use only Royal Exclusiv, but this one is almost as good, but a lot cheaper. I'm totally excited!

Super Abschäumer für einen unschlagbaren Preis. Absolut leise, großartiges Schaumbild. Sehr gute Verarbeitung und sehr schnelle Lieferung.
Nutze sonst nur RoyalExclusiv, aber dieser ist fast genauso gut, dafür aber ein Vielfaches günstiger. Bin total begeistert!
