KOOYI Sports Water Bottle - One-handed Open and Drink Travel Mug, 100% Leak Proof

Having read other people's reviews I was impressed by this product. Although a little scepticle, because it seemed to be too good to be true what people wrote, I decided to purchase this item and received it soon after placing order. Having tried it I can confirm that it indeed us 100% leak proff and its the best that I have purchased. Highly recommend to anyone looking for a water bottle.

I love the look and feel of this bottle, very smooth and sleek and the colour is gorgeous. The hanging handle is useful for carrying and the flip open lid makes it easy to open one handed so useful when running, cycling etc. Unlike many other water bottles it's a free flow spout so easy to get the water out, no hard sucking etc needed. I have on occasion found that if I overfill it that water comes out of the little ventilation hole by the spout and I have ended up with a wet face, but seeing as I am usually in the middle of a workout at the gym at the time the cooling water is actually quite welcome lol.I have generally kept the bottle upright in an end pocket of my bag however so far I have not had any leaks.I like that it's quite a narrow bottle so easily fits in the bottle holders at the gym (some of the larger bottles don't easily fit in the bikes for example) and the twist off lid makes it easy to refill.I would have liked for it to have been a little larger capacity as I do find that I have to limit how much I drink or I need refill it part way through a class, neither is ideal. For this reason I have had to give it 4 instead of 5 stars however I would buy again.

I have been looking for a water bottle that fit's in a cup holder in my car, and this meet the criteria 100 per cent, also I can use it safely one handed.I have been able to use it whilst pursuing one of my hobbies, i need lots of outside space on my rucsack and i am able to attach it securely leaving room to fit my other items. Pretty looking also.

My daughter and I both wanted a sports bottle, and whilst I was still comparing them, she bought one of these and when it arrived my mind was made up. This bottle is perfect. It's a good size and made of quality materials. The one-handed opening is useful and I have no worries about leaks. I highly recommend this for sports use or if you just want to be confident that your drink will not leak in your bag.

This flask goes everywhere with me. To and from work, the gym, on my bike. It is excellent quality, keeps water cool and tasting of water not plastic. I didn't get on with the rubber loop so took it off. Brilliant, brilliant, brilliant.

Colourful, leak-proof, one-handed water bottle.I have thrown this bottle away now after realising that there was considerable mould growth inside the bottle which is too stubborn to move without force. The bottle neck is too narrow to insert a normal dishwashing brush inside. I had been aware of a ‘funny taste’ the last few times I used the bottle but it was my husband who spotted tiny black flecks of mould. To be clear, I have alway dried the bottle thoroughly before storing it and always stored it with the lid off to let the air circulate.

I love this bottle .... I have bought several different styles to try and encourage me to drink more. This is by far the best - so much so I had to write a review (which I very rarely do) It is comfortable to hold and lovely to drink from. It's also easy to open and doesn't leak !!!!

Actually does not leak. Great product and so helpful to use one handed
