Kooyi Vacuum Insulated Sports Water Bottle 500 ML, Stainless Steel Flask Travel Mug with Built-in Straw - BPA Free

This is a very good water bottle. Mainly use it for warm water for my daughter to drink at school during the winter. The water stays warm until the end of school day, sometimes even longer. She used to bring back the water in her regular thermos bottle with the complaint that she is not able to drink warm water out of it without spilling it. This bottle solves that problem as it has a nice straw which makes it easy for my little one to drink without fuss. It is sturdy enough to withstand drops as my daughter has done it quite a few times and it is fine except for some scratch marks.

My boys love these and were very excited to get them. After using them through the summer for about 2 months I decided to write a review on them. First, they get extremely hot to the touch if they sit in the sun. The drink stays cold but I would have to make sure they were wrapped in a towel or sat in the shade. Now after using them for 2 months the red coloring is peeling off. I don't mind having silver bottles but we purchased red. I can not peel the rest of the coloring off so now I just have to wait until it comes off, which means my boys are constantly having red pieces of whatever this is all over their backpacks and hands. I was very excited to get these bottles but will not be purchasing more of them.

I have bought two of these. They are light weight but keep ice for 12+ hours, easily. The straw can be a little small and require a god suction. I love this especially for travel; the top covers the straw with is great for airplanes and cab rides. Be careful on a plane though...the pressure will make your drink fly out like a fountain when you first open the kid!

Great water bottle. I was looking for one with a lid as I don't like to expose the straw to outside elements. This one does the job. I've had it for about 2wks and it goes to the gym and the park with two toddlers everyday. Kids have dropped it hard on the concrete floor and it withstood it with just one small scratch. The straw does make a weird sucking noise but it does not bother me, sure it's the way I'm putting the straw back on.

Love the size of this bottle and the fact that it keeps my water cold for a long time. What I don’t like is the red paint is coming off and now the bottle looks like trash.

you have to suck a little hard but they are absolutely spill proof and stay cold, I got one for me and one for my toddler-love them

I don't like the way that it loses it color right away! You guys need to do something about that because with my first use it start look bad I think im going to return it!

This does exactly what it says it will. No surprises. Works well and keeps liquid very cold all day. Great price.

Does at it says on the tin- keeps drinks hot for ages. Not sure whether this part is normal (?), but have to be careful when opening the straw part for the first time after it's been refilled as it spits hot drink at you. A bit of a worry if you're not expecting it, as generally you would have it near your face ready to drink from. There is also the risk of the hot drink spilling onto your clothes.

A very good product, generally well made. It is stainless steel, double-walled but fairly light so is easy to carry, especially for my young (4 year old) grandson. It kept water chilled for many hours. The only slight problem is that the "mouthpiece" is a soft, silicon straw that is vulnerable to chewing through by a child, rather than a more solid mouthpiece that is found on other makes. This would not be a problem if Kooyi sold a replacement part. When I asked them for a replacement for the bitten mouthpiece they very kindly gave me a voucher for a whole new bottle. This was very nice of them but not the best or economic solution.

I keep this at my bedside in case I wake with a dry throat after a heavy night on the beers. Keeps water a lot cooler than a plastic bottle. I like that the top flips open at the push of a button revealing the rubber drinking spout/straw, which is convenient and easy to drink from - no doubt great if you're on, say, a bumpy car journey - no spills. At 500ml the capacity is just right. The item was a little larger than I pictured, but that's just me - I underestimated how large it would need to be to hold the best part of a pint of liquid. The design is nice too & no leaks so far.

Bought this bottle because I already have another one which my wife borrowed and liked! Nice, robust bottle, well made and stands up to being knocked about. You will get some paint chip off eventually but, hey, kids loved ripped jeans, the 'distressed' look is good. The 'straw' doesn't seem to like orange squash and is now slightly discoloured, a year on - but I guess you could buy a replacement straw if bothered, or not put orange squash in the bottle! The one hand flip lid has continued to function as it should despite my initial doubts.

This is one of the best and most used products i have ordered. Keeps my water ice cold in the summer. I only use it for water so not sure about hot drinks.If your a pleb and care more about the paintwork than the product then this is not for you! It is going to get scratched etc... just part of life.My lofe is quite active so has a lot of cosmetic damage but it still keeps my water ice cold .... longest it has stayed ice cold is from 7am to 6pm. 11 hours!!! Brilliant.The string snapped quickly but inreplace this with something more durable.
