ION8 is a British drinkware brand based in Dundee. We make leak-proof water bottles, kids' bottles, travel mugs and flasks — designed so a bottle can go in a bag next to a laptop and stay where you put it. Every bottle in the range is leak-proof. It's the thing we design for first.
Primo is designed to adapt. Every lid fits every Primo bottle, in every size — Urban for the commute, Revive for training, Roam for the outdoors. Change the lid, keep the bottle.
Triple-wall vacuum insulation with an internal copper coating keeps drinks hot or cold for up to 10 hours, and the outside stays dry — no condensation on a desk or in a bag. Primo won a Red Dot Design Award in 2026. From £29.99, with lids sold separately at £12.99.
Officially licensed team bottles, built to the same standard as the rest of the range. Same leak-proof lid, same wide opening, in team colours.
We also work with MotoGP and the British & Irish Lions.
Kids' bottles built for the bag they actually live in. Leak-proof, dishwasher safe, and a wide opening so they can be cleaned properly — not just rinsed. Sizes from 350ml.
Matching lunch bags and slings are available alongside the bottles.

A worn seal shouldn't mean a new bottle. We stock replacement lids, seals, straws and filters for the current range. ION8 is certified carbon neutral across all operations, and holds a German Design Award and a King's Award.

I ordered the Leak Proof Slim Water Bottle, Personalised, Stainless Steel, 600ml in Ash Navy — personalised with my son’s name. In fact I bought two of these. One bottle arrived with a clearly defective cap. Not a minor cosmetic quibble: it doesn’t work as it should.
When I contacted ion8, I was told my only option was to accept a replacement lid in “navy” — a colour that isn’t even listed for this bottle in this size. What I ordered, and what’s still in stock on their own website right now, is Ash Navy. A point they didnt really address in their correspondence despite me raising it.
To make matters worse, they insisted the product isn’t “faulty” at all, despite sending me a defective cap in the first place. Because this bottle is personalised with my son’s name, the expectation is that I can’t just return it and start again — I’m stuck with either a broken cap or a mismatched one, for an item I paid full price for and that should have been correct from the start.
What really gets me is the attitude behind it all: a token apology, followed by being told flatly that this is my only real
Option. No real acknowledgment, no willingness to actually fix their mistake — just take it or leave it. I would think twice before purchasing from them again. Truly disappointing
I have ordered a few times now and have been so impressed. With two young children these are perfect for on the go. They last forever, wash so easily and I love that they are not plastic!
Great quality bottles, there was a bottle missing from my order but Inah sorted it for me really quickly and got another one sent out in 2 days! Fantastic customer service.
I ordered a personalised bottle which was meant to be 100% leakproof, however it wasn’t, it leaked so I sent it back.
My score is reflective of the appalling customer service. I tracked my return and it’s been received, however no confirmation email with an update on my return and still no refund. I phoned their customer service, awful service, I was told on the phone ‘we don’t deal with that over the phone so cannot help!’ When asked what I can do the guy was very rude telling me he was busy and huffing and puffing. I have emailed them with no luck! Awful after sale service, you can tell how good a company is by how well they deal with problems! Well this is 0/10, will not be buying from them again and I will be escalating this claim!
Ordered a couple of custom bottles. They are great; I particularly like the locking caps. Not the cheapest out there but a fair price for what feels like a quality product. Highly recommend!
My leakproof water bottle was only a few weeks old and not leakproof in any way whatsoever - ION8 need to stop claiming this in their advertising.
In any case, Customer Support Representative Inah was very helpful in assisting with a replacement (without receipt), although the water bottle sent out was 500mls, not the 750ml originally purchased. As I didn't keep the receipt I regard this as a good outcome. Many thanks.
Brought 2 bottle's for my kids, very good quality. No leaks so far, hopefully they will be fine in their school bags.
Inah was really helpful and speedy in answering my queries. I couldn’t fault the service provided.
Fantastic communication and problem solved by Inah today.
Such great service! Many thanks!🙂
I placed the order yesterday and had issue with the colour of one of the bottles. I couldn't change it via the edit order link and so sent an email. There was a prompt reply from Inah who resolved it for me and today I received confirmation that the order is on its way! Ion8 have the whole package well, the product is amazing and the customer service matches also! Will always order from ion8 for my sons bottles and as gifts especially the insulated ones!
Had an issue with the bottle and contacted customer service on Friday evening. I didnt expect a reply for a few days, but was really happy to see a reply the next day from Inah.
Inah was really polite and helpful, and arranged for a replacement to be sent straight away.
Really good customer service!
Customer service was excellent. Inah responded to my query quickly and efficiently. Ion8 bottles are brilliant and the whole family uses them!
I ordered 4x primo urban bottles from ion8. We have all been impressed by the quality, the bottles are 100% leak proof and keep water fresh and cold all day.
One of the bottles started to peel back at the bottom after a month after receiving it. I contacted ion8 and I received a prompt response from Inah who offered to replace the damaged bottle. I'm very impressed with the customer service 😊
Really impressed by Ion8's customer service. The design on one of our bottles started peeling off after only 2 months of use (which I've never had with one of their bottles before) and Inah arranged for a replacement to come straight out to me. Ion8 is a brand I liked already and they impressed me again today!
Had an issue with a bottle that was sent. I sent something through with photo evidence. Inah was incredible and dealt with my query in super sonic time. My initial query was sent at 11:30 PM on Saturday and the next thing I know I had an email through with a replacement order receipt at 4am on Monday and it was at the door by Thursday! Just incredible service. I had no expectation of a complete replacement but very much appreciate it. Inah was an absolute pleasure in the couple of exchanges we had. Thank you very much to Inah and Ion8. Our family were loyal customers anyway but this has cemented it!
In November last year bought the flask and water bottle, which I use daily, the flask has never been in the dishwasher always washed by hand but the seal has gone, I took photos and emailed, had a response to say all sorted and it arrived, coffee is no longer leaking from my flask. You get what you pay for, don’t hesitate to buy this product coffee stays warm all day, inah assisted me very grateful :)
I bought two water bottles for my daughter and received an extra one as a gift. Unfortunately, none of the seals works properly—water leaks out when the bottles are in a backpack and even spills while drinking. I also purchased straws for the bottles, but every time we open them, water jets out unexpectedly. This is very disappointing.
Really bad customer service. The free gift options aren't compatible with the water bottles I purchased. When I emailed to have this replaced I was told that I couldn't and that another lid would be available (not in the same style) and I would have to pay for postage. I dont see why the customer has to pay to correct something that this company has done wrong. A big company like this you would think it would be no issue to send out a replacement as a gesture of good will. Unfortunately not.
I ordered ION8 bottles and the payment was successfully deducted from my card. Five days later, I was informed that my order had been manually cancelled and that I should simply place the order again.
The bigger issue is that no refund was actually processed, and I was given no information about when I could expect my money back.
When I contacted customer service, Stewart Cowie sent me a screenshot claiming that the order had been refunded and that the order had been cancelled after payment due to a stock allocation/fulfilment issue, despite the payment having already been successfully taken, and that, if I couldn't see the money, I should contact my card provider.
However, the screenshot he provided clearly shows that the order was manually cancelled and that the refund is still pending — not processed. The cancellation email I received from ION8 also indicates that the refund is pending.
It is extremely frustrating to be told that a refund has been issued when the company's own documentation shows otherwise. If a refund is still pending, customers should be given a clear explanation and an expected processing timeframe rather than being directed to their bank.
I expected much better customer service and transparency from ION8. I would strongly recommend improving the refund process and, most importantly, providing accurate information to customers about the status of their money.
