fantastic product - it keeps the water temperature (I've only tested it cold because I bought it in summer) all night long (I keep it next to me in case I get thirsty during the night and in the morning, whatever is left in the bottle is still cold. I find the mouthpiece made of soft material (not hard plastic), with rounded edges, especially nice and very convenient. The mouthpiece and the straw have larger holes than usual straws, so more water passes through when you sip.

A water bottle that empties when it’s closed, first time I’ve seen that. It has a silicone straw and when you close it, obviously it can’t close 100% and the water leaks out if it’s not upright. Unacceptable, money wasted

very high quality, comes with 3 nozzles each in a separate cap (nipple, screw cap, and free flow) with 2 flexible plastic straws for use with the nipple and a cleaning brush for the straws. I have the 750ml and it is just enough for the beach. I highly recommend it.

Very convenient, Keeps water or anything else cold for many hours. I have never used it for hot drinks, but I assume it would work just as well. When I say many hours, I mean that after 8 hours the water from the fridge will still be very cold. If it had ice cubes, they probably wouldn't have completely melted yet. I didn't like that after about 1 year the straw broke and now I use it without it.

It is very good in insulation but it makes noise when you drink and after a while it leaks, so you have to change the plastic mouthpiece you drink from. Fortunately, it has replacements, not so expensive

It is very satisfactory, and definitely worth its money, but.... I mainly use it at work, and my job requires me to wear a white shirt..... Well, when I sometimes go to open it to have a coffee, it leaks from the inside out, and it has stained me two or three times...., resulting in me having to change my shirt...... It is the only thing that I deduct one star from.

Tested on cold beverages. It keeps the drink cold for many hours while being exposed to the sun. The outer coating is non-slip.
The opening button of the "nipple" is very practical. You can open it to drink with just one hand.
The large opening on the mouth is also practical. You can easily put large ice cubes and it facilitates cleaning.
It is not dishwasher safe.
Update one month later:
Suddenly, the "nipple" lost its seal.
If it tilts or turns upside down, water starts to leak. There is no way to fix it. Unfortunately, it is a waste. Unacceptable and a shame.
Update 13/01/2020:
Aesthetically, it remains unchanged. Finally, there are spare parts. So the problem was easily replaced with a few money, before 9 months. Since then, there have been no more leaks.
