Great water bottle, had it 2 months now,, it the correct size !!! It's well made, great flip top,,press the open button and the top flips open, push the open button up and it clicks and locks the flip top so it can't open in your bag by accident,,it has a carry ring/finger holder that you can fold back into the top area,,,, the water bottle does not leak and it's nice and solid ,,,not thin plastic,,, so this bottle will last for years !!! Easy to drink from as there is a tiny suction hole on the top so the water flows out easy when you drink, this is a great 1ltr travel water bottle which is not to big and not to small I have had chilled mint green tea/orange juice cordial /water in mine and it works great for all,,, I use mine for the gym and sauna,,,,and I am very happy with it as it is just well made and a quality item,, would definitely buy again and definitely recommend. !!!!

My last one finally gave up the ghost after 4 years but likely would have continued had I not dropped it whilst full! Replaced with the same {improved} product. Light weight and looks smart and does not leak. Fair price too and would certainly recommend, in fact I bought two!

[Update after 2 years] I've carried this with me and used it non-stop for 2 years. It's been very very good. So easy to flip open one handed and grab a quick drink (useful in the car). It started leaking a little after quite a lot of use. We have very hard water and this could sometimes be fixed by giving it a thorough clean as scale does build up eventually. I then bought some replacement seals, but these never fixed the leak fully. It was still very usable, but I couldn't trust it not to leak if lied down.
Now at 2 years the spring on the catch just broke. That's probably not surprising after the amount of use it's had. It would have been nice to be able to buy a replacement spring or even lid. Ion8 claim to sell these but they’re not currently available and I don’t know much they’d be.
They also (from pictures) seem to have moved away from the hand loop/strap and now only have the solid plastic finger loop on the lid. That means buying another is not straightforward as I much prefer the strap (perhaps fit my own to the loop).
—————————
I’ve had a 650ml version for well over a year. I use it all day every day. It’s all good. The lid is easy to use one handed and can be opened and closed quietly if needed. It’s easy and quiet to drink from as there is a separate vent. That sometimes means you spill some water out of the vent if not careful, but not a big deal. The handstrap is fine, but for me (medium man’s hands, smallish wrists), it’s fractionally too short to put my hand through and then hold the bottle. A minor annoyance. We have hard water and it’s picked up some scale on the bottle just under the cap which is a little tricky to clean because of the shape.
None of these minor things have put me off ordering 1 litre versions for my wife and I. I first of all ordered another make on Amazon which looks the same in the pictures. In practice, I had put this back in the box to return within 5 minutes as it was a cheap knockoff. Almost identical looking, but the cap was cheaper plastics and the hinge and spring were flimsy and did not work well.
I’ve just received our two ion8 bottles and wanted to just mention that the description is a bit misleading. It says carry strap/hook in the detailed specs and you’ll see in one of the photos a picture of a hook rather than the strap. In practice we received one with the strap attached to a ring on the bottle and the other came with a hinged plastic loop on the lid itself. Odd.
The expect the one with the hook/loop will work better as a hiking bottle as it could be attached with a carabiner if needed. But not as easy to carry the rest of the time. It would be best if they came with the loop and a strap which could fit this.
I do think the description should be clearer. I’m not sure if the difference is colour specific. My blue bottle has the strap and my wife’s aqua bottle has the loop. You can see the difference in the main photo when you switch colours but it’s not immediately obvious.

Great quality and trustworthy company as I’ve had a few of their bottles now and they’ve all been great. The purple is a lovely colour too. Definitely recommend.

I love this bottle although it is very difficult to clean as it is thin and tall. The button is sometimes a little bit temperamental but it doesn't bother me and I'm glad it has the extra clip. I like drinking from bottles like this because it can just be poured and it's never leaked on me, seems to be completely leakproof.

The Ion8 1 Litre water bottle is a water bottle made by a company called Ion8. It holds 1 litre of water.
It is a sturdy water bottle, made from a firm plastic-like substance, with an easy to use grip that – I personally feel – is more of a gimick than required for the function of the bottle, but certainly does no harm. I bought the black bottle so the water level on the side serves little function other than making the outside of the bottle look less empty.
The lid flips open using a latch system with the lid on a spring, the locking mechanism folds over the latch to stop the lid accidentally opening in a bag.
Whilst I haven't actually performed the rigorous scientific tests of filling the bottle and turning it upside down with the lid closed to test the "leak-proofness" of the bottle, it has fallen out of a bottle holder once or twice to the ground and still did not leak water.
Some reviewers have complained about spilling water on themselves when attempting to drink from the bottle, if you suspect that you will not be able to handle the complex task of drinking from a water bottle, might I suggest getting a childs sippy cup and working your way up. It should be noted that turning the bottle all the way up to drink out of is both silly (because gravity exists and will invariably try to drag the water out of the holes, causing the aforementioned and oft- complained about drenching) and unnecessary: it is perfectly possible to get the required amount of water out of the bottle by tipping at less than 180 degrees.
Admittedly it is a tad more expensive than alternatives, but is equally: easier to use, more sturdy, less likely to flake inside (because there is no inside material to flake), and better designed than others.
In short, for people looking to buy this, I would suggest this logic: If you want to spend a fair amount on a bottle that will last a long time, buy this bottle. If you resent spending money on something you risk getting drenched by, buy a single use plastic bottle from your local supermarket. IF you've got this far through this essay of a review and still aren't sure: just use a glass and fill it from a tap.
