Ultra fast delivery, as every time, but this time I received a product that was broken and I didn't even need to open it to realize it since the ordered part was literally shattered (pump rotor). Good communication with the after-sales service who offered me a solution, but never implemented it.... So, yes, for this time... totally disappointed with this experience.

I received the ordered pump (over €190) but the product was a demo product and I had to return it because it was impossible to connect. I am still down and I hear that Zoanthus is finding a replacement solution!!

Non-existent after-sales service, no response by email and impossible to reach by phone for weeks. Purchase of the Milwaukee refractometer and a calibration solution. The refractometer does not read the correct value.

Error in delivery, the item received is not compatible. I received the item in 7v width 11.5, ordered 9v 14.5cm. Therefore, I wish to return this item which is useless for me. Please let me know the procedure for returning this item. Thank you in advance, Annick Ferrari.

Order placed at 11 o'clock, additional order placed 30 minutes later. The second one was not honored without explanations until I inquired about it. After a week, I was told that additional shipping fees were due and I was offered either to place an additional order by paying the shipping fees or to get a refund; I requested the refund, and I am still waiting for it. I would like to point out that I have ordered over 3000 euros worth of various materials and products in the last 2 years. Business policy needs to be reviewed, in the meantime, one less customer.

Hi, in fact the answer should have been yes and no! But let's put things into perspective (I will continue to order from you) but when we order an ICP test it's because it's urgent and we want to stop the loss of our animals... respectfully! Olivier Bruaut

Regarding order no. RKQDXKPVL which, to date, is still "in preparation" despite the payment being made on 07.05.2025, it is presumed that it will never arrive. I am therefore forced to order another product to avoid losing the money already paid; the situation is very unfair also because before placing the order I wrote to you and you assured me that it was in stock (1 unit) and even earlier I had checked on your site and the product was listed as available in 2 units.

Hello, I received order WECXPEDBD and one of the items was incorrect. I ordered MILWAUKEE - ORP Solution 200-275 mV - 230ml Reference: MA9020 and I received MILWAUKEE - Storage Solution for pH and Redox Electrodes MA9015. I would like to receive the item I ordered, how do you plan to resolve the issue? Best regards, Luis Valadares

Is it really a glue for corals? I made 10 cuttings a month ago, I bought this glue for more convenience.. 2 days after gluing the corals, I have 9 dead corals, the only one that is alive is the biggest, the smaller ones didn't survive. I'm disgusted.
