Love that it’s easy to drink from and sturdyI have two older bottles from this company and they are great on the bike and general purpose use. On this one, the cap is very stiff,: so hard to open, it's frankly a real pain. Not sure why they changed the design, but and not sure why this package shipped from the UK. I won't return it, for the price I can get some use from it, but look elsewhere if you want a bike bottle you can actually use while biking.Buena. Pero no conserva bien el frío.These are great bottles! Works in bike holders. Holds about 27 ounces. Good caps, and bottle weight and thickness. Quality plastic materials will last for years. Don’t mind the advertising at this price. Local bike store charged 3 times the price!The main function of a bike water bottle is to hold water without leaking. Sadly, this bottle fails the primary function. It leaks through the threads so even when vertical it leaks if shaken up in a bicycle cage -- which happens a lot when mountain biking.Lo usé un día en un recorrido fácil y apenas se puso ya se dañó y fue difícil beber producto pesimo otro q compré en pack 2 más barato la calidad es mejor no lo recomiendo mejor reembolse mi dineroAnother water bottle but I like this one quite a bit. The cap seals tight and does not leak. Most other bottles do. The squirt valve is very functional also. Good price and you cant go wrong.I like the measurement markings on the sides of the bottle but the bottle leaks. I tightened the cap as tightly as it would go but the bottle still leaks. It even leaks in the verticle position, while the bottle is in the bottle cage. This is a big disappointment, especially with an SIS product. I I would have returned the bottles butmy return window was closed by the time I found out how cheaply made these bottles are.Could this be the perfect bottle?Only time will tell.All my bottles had got old,And really started to smell.I promptly ordered a new one,It was a mere £3.99.I really love the design of this,That I've ordered another time.No more getting thirsty,When I'm out on a ride.I love my 800ml bottle,It's on my bike with pride.I use this bottle a lot. Delivery was great, as I was getting it delivered to a temporary address and it arrived exactly when it said.It also has the right number of holes so the water comes out only where it's supposed to! Like with any water bottle you have to close the lid so it comes out exactly when it's supposed to. With the lid closed it does keep the water in, which is great as I'm pretty tough on this little bottle...Almost nothing surprised me more when, after a couple of rinses like with any other bottle, I took a swig of much craved water and it tasted exactly like water!Not only does this bottle hold my water until I need it, it also delivers it at the right time tasting like it did when it went in.I'm glad I bought this.Water bottles ey? Who would have thought it would be such a palaver to find the right one!?But I may have found it with this one:Nice squishy plastic (but firm enough), so it’s easier to squeeze the water into your mouth!Nice soft cap that you can open with your teeth so you can keep one hand on your handlebars.Nice little design (ridge) that enables the bottle to sit in a water holder with ease. Fits my Vico Carbon Elite perfectly!!Nice wide opening, making it easier to fill - and to fit ice in for those extremely hot days out!Nice price - I.e. relatively cheap so if something does happen at least you can get another one, without breaking the bank - and at a cheaper price than a more expensive bottle.BPA free! Which is a good thing.Flow rate is pretty good.The bottle is marked to help you measure out SIS supplements if you are using.Also…sounds a little odd to say, but when you need to quench your thirst it actually TASTES like water (if you have water in your bottle obviously - if you had Lucozade in it, it would taste of that!!). Some bottles can add a plastic-y taste to the water - this one doesn’t! I use a hydration backpack as well as this on a ride, and that definitely has a distinct plastic taste to the water! So it’s nice to get the pure taste from at least 800ml (probably a little more if you fill it right to the brim).Also as it’s quite squeezable - if you’ve got anything left after a ride, you can have a decent water fight with your mates!Onto the bad points;I’ve seen from other reviews that the bottle can get discoloured if you are using a coloured fluid in your bottle - this may be the case, but it doesn’t affect the use - so far mine has stayed the same clear colour due to me just using water.Also other reviews have stated that if you drop it on its head, you will snap the nozzle - my advice is don’t drop the bottle! Although if you do have butterfingers and it does snap it’s not a hugely expensive cost to replace.Overall a pretty good bottle and a piece of kit I will always definitely carry round with me when out on the bike! I tend to use this mountain biking, and the only thing I’d suggest as an improvement is probably a nozzle cover to keep the mud and stuff out of the nozzle, but this would obviously make it a tad harder to open on the bike.Would I buy this bottle again? Maybe, although probably not as since I purchased this, SIS have released a slightly larger 1000ml bottle in the same style - and I’d probably get that instead for that little extra hydration!Thanks for reading - if you found this helpful, please let me know by clicking below. ?Muy bien, es importante tener el cuenta que el agua se pone por dentro, no chupar por abajo ni morderlo porque se rompe, no dejarlo al alcance del perro, admite agua, voll damm, cubatas y gasolina sin plomo aunque esto último puede provocar accidentes, yo no lo haría. Cumple su función y ya está. El resto són delirios que me vienen de vez en cuando.Had previously used SiS bottles for over a year at a time with no issues. Not sure if have a bad batch or general quality has been really reduced but the two brand new clear bottles I bought last week from Amazon have discoloured badly already - that’s with handwashing only, not in the dishwasher. Compare to a 6 month old High5 clear bottle in the photo.
