The filters arrived without the required parts for installation. These have now been ordered and installation is booked again for next week. Very dissappointed unit could not be installed because requisite parts were not supplied.

Think its pretty damn stupid to charge £200 for a hydrogen bottle and not include some blue drops so you can actually test its working. But no, they want you to spend £50 on the drops on top of what youve paid. I HATE corportate greed over customer satisfaction, its so wrong

Our filter has always made the water taste chlorinated and customer service was very unhelpful.

I get 5 10min bottles then I have to fully charge for at least 2 hours to get a full battery again. £180 to wait around on hydrogen water? Is it worth it? 👎 NO waste more time charging when I can just drink mineral water and hydrate just as quick in the time it's charges again.

Very disappointing that the "requires maintenance" button is still flashing after replacing the filters. Cartridges are expensive. Lots of water gets wasted on every fill up.

I paid for 2 sets of filters. Waiting time was long. After 20 days I received only one set...

I am pleased with the bottle but very dissapointed in the battery performance. Despite following instructions for charging, it only seems to last for a few cycles and then needs charging again. Considering this cost me £200 I feel sumwhat diddled!

The water always tasted bad with chemicals taste for the first whole month of using new filters. After one year of using the machine, i have emptied it and stopped to use it for 2 months, then i have sanitised it properly, changed new filters - and for 3 weeks in a row i am drinking a water with the mold and plastic taste - its too expensive machine and filters to have so much issues with it - not recommended

I feel compelled to set the record straight given all the positive reviews here. The Osmio water filter is not fit for purpose since the company expects customers to descale the entire appliance which involves removing dozens of tiny fiddly screws and reassembling small parts. I was not offered adequate customer support and had to cut my losses within less than a year. The appliance is expensive and high maintenance.

Unfortunately we received the wrong order and when ringing up to notify the problem the customer service lady was rude.

Telephone communication wasn’t helpful or easy to hear. New filters and cloudy water so I’m not sure if my purchase was correct! That’s why I phoned and wanted to purchase directly.

We did not find any difference in the water quality after changing the filter, not sure why it is supplying water without any taste change.

Owner Mark Kent has zero respect for customer. He wouldn't listen and talked over me and was very rude and inpatient. Indra filter 400 stopped working after 4 weeks he said it was the plumbers fault without listening to what I was saying. He referred to my plumber using swear words telling me he 'ballsed it up', despite me trying to explain my plumber was very good and had installed per guidance. I was very polite and didn't even ask for full refund, which I'm entitled to under consumer rights and one year warranty, I asked for a discount on a new one. He told me to send an email to info @ osmio, to ask for a discount, saying he had nothing to do with this and could’nt make these decisions. He knew I had already sent various emails to this email in the past 2 weeks which he had received, and I had spoken previously to him about the matter the week before. He told me the generic email, info@ osmio, is the only way 'operations' would receive my discount request as he had nothing to do with these decisions. He basically told me to write to the general email to fob me off, knowing I had already sent various emails to this address over past 2 weeks clearly stating the problem. He then admitted he was the managing director, when i asked if I could speak to a manager, and hung up on me, after asking sarcastically 'is there anything else I can help you with?', (after being rude, unhelpful and not offering any solution). This was my second conversation with him today after 2 weeks ago when he was also rude and talked over me completely. He practically snapped my head off and I was completely polite to him. He would not admit that his equipment may be defective or damaged. It was installed correctly by a plumber who installed them before. He then refused to speak to me when I called back. He was very over bearing and rude and talked over me through the whole conversation. A very unpleasant man. I am now left 260 pounds down with a faulty casing unit that lasted 4 wks. The filtered water was very unpleasant too. Im very upset with whole experience. I would run a mile from this company. If you have a problem with anything the owner he will just talk over you, not admit any fault and if you disagree you will get hung up on. When I tried to call back he refused to speak to me and sent an email straightaway saying he will not offer me any discount. This was straight after he told me he couldn't make these decisions. Save yourself the bother and money. I wouldn't trust this guy as far as I could throw him. Never dealt with such a rude and dishonest tradesman, maybe he's this rude to all women as I see the review below is also a woman he was vile too. The products also appear to be sub par, and your screwed if you think their tech team will help as you usually get through to this unpleasant man.

No issues with the product but Mark Kent is the least customer-centric and rudest owner/founder of a company I’ve ever had the misfortune of dealing with!! I called the tech team with a simple question to do with the fairly complicated process of early descaling my Osmio Zero as a result being in a hard water area, and unfortunately he answered. Bearing in mind I’ve only had to descale once before so it’s not yet intuitive. He was impatient, patronising and downright rude, including telling me that I was the only person not to understand the video instructions and that I had it wrong. Well, when he looked at the section of video I was referring to he realised that HE had it wrong!! No apology, no acknowledgment, just more rudeness. It’s a shame as everyone else I’ve dealt with in his company has been the polar opposite. Polite, patient, helpful, kind. It’s no wonder he is losing staff. Had I known what an asshole owned this company I would never have invested over £500 in it and would’ve looked elsewhere for a reverse osmosis water filter machine.

You never sent me the gasket filters that go into the first pod. The first one your water enters. Now alls I have is the ones you sent me floating free inside it’s pod, not happy at all

The machine is prone to regular failures and I'm disappointed the company Osmio Water does not accept the warranty of the product due to hard water. Simply unnacceptable. For the cost it is not worth it. Never again.

Hello Mr. Kent, the order of the two UV glass tubes with a closed side has arrived very well packaged. But these tubes are way too long and I can't use them. Despite my clear description of my glass tubes with detailed photos and size units, your team has not succeeded in delivering the correct tubes to date. Worse yet, despite my communication with your team, I'm getting no response. My investment is worthless and in the meantime I cannot repair my UV water installation. So deeply disappointed in all aspects. Order No. 1000088142.

Only 6 of the 7 pieces arrived. I wrote immediately upon their receipt last Wednesday (it's now Monday) and have had no response regarding the issue. How will Osmio rectify this issue?
