Great affordable option!
Love this handheld! Wish it had a pocket but everything else is a 10/10. Super easy to tighten it on your hand as you drink. Comfortable to hold. Been using it for about a year.

Great for long runs in summer
These are amazing, I still use them constantly and have them after a few years of using them. I use them on all my long rungs during summer marathon training and they’ve held up well. You do have to make sure to wash them and let them dry properly. Specially if you are loading them up with drink mixes. Amazing value for the price.

Beware These Leak
Unfortunately, these bottles leak. Specifically, they leak between the top of the screw on cap and the top of the opening of the bottle. Ideally, the caps should have an elastic O-ring to help seal with the bottle, but they don’t. This means that if you squeeze the bottle or apply any pressure to the sides, your liquid will leak, no matter how tight you tighten the top. I purchased two of the smallest sizes and they both leaked, meaning this is likely a problem inherent to the design itself and not just a manufacturing issue.

Good at first, lids didn’t last. Happy with seller
I liked these for carrying gel on runs, worked just as I had hope. The lids began to not fully snap shut after 5 or 6 runs. So, they just didn’t last very long they aren’t usable since the lids are leaking. If the lids were better quality I’d give 5 stars.Edit: The seller; Triwonder, noticed my review and reached out to me. They had asked for photos or videos of the issue I had with the bottles but I had already thrown away the bottles. They still decided to give me a partial refund for the bottles. I have several other Aonijie products sold by Triwonder that am very happy with. Good seller, with mostly great products. These may also be fine, I might have gotten a slightly defective pair. I do have other larger Aonijie bottles that all work well and have lasted as would be expected.

My new favorite running waterbottles!
These are excellent handheld waterbottles and are my new go-tos for my long runs. They hold the perfect amount of water (500ml) and work well with one bottle in each hand. The fabric carrier that holds the water bottles are extremely lightweight, comfortable, and allow you to keep the bottles secure without requiring you to grip the bottle tightly (saving energy). The hand hole is adjustable to keep the bottle snug as you empty the bottle, and the thumb hole is useful for keeping the bottle secure in your hand without actively squeezing it. The carrier also has a separate pocket for storing keys, cash, etc. I haven’t tried carrying a phone in this (more weight than i prefer to lug around on my runs) but it appears it could accommodate one (maybe not the largest though.) The bite valve is very secure and doesn’t leak. Great design as a squeeze valve would surely leak- this one requires a light bite while you squeeze the bottle to work. Overall a great performing design and an excellent price.

Works great! Fits in yoga pant pocket!
Love these for races and just longer runs in general! They don’t leak and fit pretty great in my side yoga pant pocket! ð
Eimear –
I have been using these for years now. Never leaked, i keep them in the freeze between uses & there is no taste or smell from them. They are so convenient, i have used them in my hydration pack, waste belt & also put one in my running shorts pocket, for short warm runs. The fact they roll up when empty is good for longer runs, better than hard bottles.

mi è piaciuta molto questa borraccia morbida ,con la quale si può bere facilmente,esercitando una leggera pressione sul contenuto interno di acqua. Non perde assolutamente,e la valvola per bere funziona perfettamente.dopo averla risciacquata la prima volta, e messo l’acqua all’interno, non ho avuto nessuna sensazione di plastica o altro.l’unico appunto che potrei dare,è soltanto che non ha la misura di millilitri della quantità di acqua interna.
