Tres bon produit au regard de la concurrence. Mais un peu bruyant et quelques tout petits soucis de précisions dans les dosages.
Mais ce sont des détails qui n'entament pas la qualité du produit !!!

Nice quality/price ratio. Not so accurate.
very easy to program

Very good customer service. Good product. It is working but
1) one pump make strange noise.
2) not so accurate
but still acceptable. Must be investigated.

Nice quality/price ratio. Works perfectly well with some maintenance. Definitely worth it.
I have it in a 400 lts tank with soft corals, Lps,Sps and fish.

Very good dosing pumps...works OK.

CONS: very hard buttons, not confortable

For the price of the unit it seems to work pretty well. Wish it had four heads like the competition. I would recommend it for sure. I will be placing an order for the expansion unit soon.
