I bought 4 of these with engraving for 4 of my kids- ages 5, 4, 3, & 1.5. So far- love them. With young kids I was trying to find something to steer them away from sippy cups when we are on the road. We only use them when we go out & for water only. I love how cold the water stays, and it's so much tastier than drinking from plastic- always hate that plastic taste. The kids love them too- they love having their names on them (which also helps with reading skills). And they love having special cups all their own- it helps get them to drink more water too! As expected with young kids, they are tipped over & dropped often. If not closed properly they will drip when overturned, but my 5 & 4 year olds are able to open & close by themselves.
Love the Sport top lid. It makes it easier to use the bottle in the car. Wish it would keep the liquid room tempurature but otherwise it really helps cut down on using plastic disposable water bottles.
I bought 2 of these - one for myself and one for my husband and we both agree these are the best. We exercise and the canteens fit in the holder on our treadmill. We also use it for our regular exercise sessions. I also have mine by my bed at night as I wake up dry. It does not spill when tipped over. The whistling the others have mentioned does not bother us at all. All pluses for this product ---
This was a great gift for my parents, they are always on the go with their water bottles. Now they have safe, clean kanteens to keep with them everywhere
