Fantastic had an avex after a while the popping up rubber part developed a tare this one was better you can replace the parts unlike the avex also it keeps the liquid cold longer if you put ice cubes in they will last for 24 hrs

Great robust bottle and keeps water cool for a good few hours good item very happy with the item overall

The only drawback id mention is that the seal can be a little tricky to keep in place on the lids
