Work great for a low price

This is a good alternitive it works great and price is good. Wires to short and holders not fantastic, but it does what it needs to do

it works great for the price, placement in the tank is a big part.

It just works with no problem at all. stream is in fact slow, but this is, depending on your placement of the pumps, very helpful.
Works good for 120x50x50cm with additional stream of the sump pump.
I would like to see the same kit with just some stronger pumps for bigger aquariums.

I'm happy with it, it works fine, and does the job, the only comment is the rubber cups start to give away which need more attention! the magnetics cups could be a better option but more expensive!

good wave action for a cheap price

for th price it has, it's a good product, i've no more sedimentaton on the reef and the corals have a movement more natural!!! :-D

donne un effet de balancement naturel aux LPS très sympa , l'alternance des pompes pourrait être plus rapide , bon rapport qualité prix ,
pour ma 2eme commande , l'envoi est toujours aussi sérieux (1 semaine pour réception )

very slow and low stream
