Ion8 Sports Water Bottle, 750 ml/24 oz, Leak Proof, Easy to Open, Secure Lock, Dishwasher Safe, BPA Free, Flip Cover, Carry Handle, Soft Touch Contoured Grip, Easy Clean, Odour Free

Brilliant bottle. I got a few of these in different sizes for my boys to use at schools and leave on poolside to sip during swimming. Very good quality, no leaking, easy to carry around, water flow smoothly and just the right size for mouth, looks good too. Most importantly easy to clean. Not like the bottles we used before, the mould trapped in the sipping area and couldn’t be reached to clean, have to throw away quite often. For this bottle there’s nowhere for mould to hide, great for long term use.

I've had this for months now and it's my constant companion. The lockable lid and no spill are ideal for journeys. It's comfy to hold and generally a good water bottle

I got my first one from another retailer about 2 years ago. It has been so good that I bought 3 more, for my wife and 2 sons just recently. I thought they would come with a cloth strap (like my old one), but the 2 that have arrived so far have a plastic ring at the top. Actually this is easier to clean and more hygienic and I think this could be an improvement in the latest model. But I still like my old one with the carry strap. I don't know what the most recently ordered one will come with - strap or plastic ring - it depends what's sent, but I'm not so sure the photos on Amazon's site are a true representation of the product so I have given it 4 stars.This really is, however, the best water bottle I have ever owned. It is well designed and engineered. There is no vacuum when you drink, but if you tilt it up too much it might just leak a little from the air hole when you drink, but you'll soon learn how to stop this.My old one has never leaked. The silicone seals have performed well over a long time. I have NEVER put it in the dishwasher. I would NOT recommend this.It is not an insulated drinks carrier but the material that makes up the bottle walls is substantial, so heat loss from hot fluids, or heat gain of cold fluids would be slow.I would not take this on a super light backpacking trip as there are lighter options, but I use my original ion8 every day (I take it full of cold filtered water to my bedside every night). I love the opening mechanism and the lock feature.In my opinion this is worth the price. I would be surprised if it failed but I see that some people need replacement silicone seals. Perhaps they are putting it in the dishwasher which, as I say, I would NOT recommend.I would recommend this product. It's well designed and we'll made. I'd be surprised if you were disappointed. I understand an added bonus is that it fits bike carriers (but I don't cycle), so can't comment.

Ok so mine didn't come with a £50 note inside but now I have your attention...We have three of these bottles, 1x 750ml for me and 2x 500ml for the kids. Hopefully this review will help others as I wasted a good hour looking through other peoples comments as usual!They do not leak if the lid is screwed on properly (opening button should be in line with the ion8 logo). If you fill it up, tip it upside down and shake it no water comes out. They have also not leaked in my kids bags and lets face it, those bags will have been at every angle throughout the day!The breather hole is a good thing, do not be put off by this - it is not a design flaw and you do not have to drink out of it in some silly way. Never have I, or my 6 and 9 year olds, had any water come out of the breather hole when drinking. It actually helps you drink more due to the water flowing out quicker than normal bottles.The 750ml bottle is 750ml, not 650ml. Someone complained in a review saying they did not get what they ordered with a photo of the approximate capacity markings on the side which only go up to 650ml. This is the case but you can fill it past this line, I'll let you guess by how much more :)There is only one negative with all of these bottles and that is the hand strap that comes attached. It's made from material so even when the bottle is dry after washing, the strap stays wet for ages. None of us have a use for it so just took it off, definitely didn't warrant the loss of a star.So there... I hope that puts to bed all the questions that you didn't realise you had until you read other reviews :) It's a non-leaking, non-toxic water bottle, don't waste any more of your time looking through more reviews, you obviously need one so just buy it!

I have bought several of these bottles on the recommendation of family members who told me this was the only bottle they had found that doesn’t leak. So I was a bit disappointed when one of my lids started to drip. I found a link on Amazon to the company’s help page & contact centre. There I found that a tiny seal on my lid was missing. I sent a message. The next day I got a delightful reply with the promise of a free replacement seal which arrived a couple of days later. Also included in the email reply were links to care of the bottle & where to find replacement seals in the future. I have looked these up & they are very reasonably priced. Unlike some other companies there was no request to write a positive review, I am doing this as I rely on other reviewers to make decisions about buying products.

Having used this bottle for a few weeks now, I can confirm that it has proven to be leakproof. I have only been squirted in the eye once through the air hole and that was when I very stupidly tipped the bottle straight up into the air, despite it being very full! Definitely user error rather than a design fault. It’s lightweight, easy to clean and arrived odour free.
