I'd previously rated them 5* supplying spares and assistance, however my recent experience was anything BUT 5*. I'd - directly from the UK site - ordered a couple of controllers and sensor(s) kits totalling £239.00 for those items, along with some other fans and sundries making a total of a little under £300 after discounts. The controllers duly arrived with the fans and sundries but not with the additional sensor kits which make the best part of £150.00 of the total. I duly, and politely, emailed to ask about the sensors and got told they would be delivered in December. That was, from date of Point of Sale, at least 3 weeks later. There was nothing on their site to tell me that this was the case, and nothing proactively mentioned to tell me after ordering, either.
Long story short, I bought them as kits and needed the additional and optional sensor kits. Waiting 3 weeks was not an option in the circumstances but, there is more! FWD-FAST 3 days, grudgingly accepting the delay on the sensor kits, thought I would at least set up the controllers and basic/included sensors, only to realise that the controllers I have been sent do not connect to Wi-Fi. The older model of these controllers does not connect to Wi-Fi, which seem to be the models I was sent. If you go on MH's website and search for the older model you cannot buy it in the UK, only their 2025 model with Wi-Fi but I digress; I emailed them again, following contacting them about the missing sensors, 4 times in total and those emails went into the ether... a vacuum; I had no response whatsoever and at time of writing this I have still not heard back from Mars Hydro.
If, by dint of my own issue, these controllers (controller43) ARE the correct ones, they haven't confirmed or helped me to understand them; there are no instructions for Wi-Fi connection supplied with them, just the basic stuff for example. I am left floating in the breeze with no information to help.
I responded to their original email about the delayed sensors, too. Tumbleweed. Nothing. No help, no confirmation, nothing.
I was sold sensors that were not in stock and I was not told about this; I received seemingly although not confirmed older controllers that don't appear to be Wi-Fi connectable AND if they were, I have received no help anyway.
Summarising, I have now approached Paypal and raised a dispute. This is a prime example of customer service that should be embarrassing to them. A simple response to my query about the controllers would have sufficed as would being told the sensors are not actually available, or at least would be 3 weeks' waiting for them, giving me the choice at time of purchase. Instead, 2 hours of writing emails, 30 minutes raising a dispute with Paypal, and now, writing this review, which pains me greatly; I have a lot of MH kit but that was bought via third party sellers.
I would suggest never buying direct; use a 3rd party reseller who have clear indications of stock levels, rather than leaving it to whatever drop-shipping warehouse MH employ here in the UK. The limited support is extremely disappointing.
I just needed information and being told the truth about stock levels. Being ignored is painful.
Dec 2025 Edit
I have now finally been contacted. Let's see where this goes.
April 2026 Edit
As can be seen it took almost a month to respond to my original review! The sensors took 6 weeks to arrive and the information about the controllers satisfied my concerns that I had been sent the correct ones. I emailed them to say as much
Summarising, I stand by what I said in respect of buying through a reseller with stock. Customers should not be waiting days and weeks for items out of stock or information or answers to their queries.
I won't use their filters again (genuinely rubbish) but the controllers and sensors, once installed, are decent.

I had an issue with the order I placed and wanted to return the item. Their was no phone number to contact anyone - nothing but a customer service email address. I was very skeptical at best
That said, I reached out to their CS and surprisingly received a response the next day from an agent names Esther.
Esther was delightful and extremely helpful and thorough. She was a pleasure to deal with and made my entire experience with Mars Hydro incredible. She facilitated the return, sent a return label and saw to it that I received my refund.
She was GREAT!
If you have any issues with anything you buy from Mars Hydro - they will back their products but more importantly they support their customers
