This is exactly what I needed for Zumba!

This is exactly what I needed for Zumba class because my blood sugar can drop suddenly and it's best for me to have both a water bottle and a sugar water bottle. The bottles are easy to open and close quickly, and the clear plastic shows me exactly what and how much is inside. (I use electrolyte powder to color the liquids.) My one warning is the moisture seal on the inside of the cap. I was cleaning them quickly one day and had the white seal drop out. I didn't notice when it did and the bottle started to leak as soon as it was on its side. I tested the other bottle, and the seal doesn't drop out easily, but I must have scrubbed or something to loosen it. Not a problem, the bottles are not expensive and now that I've bought a replacement, I'm more careful about how I clean.

Multiple uses

I haven't actually used these as a water bottle but for kids activities and for camping. I used them to make water sensory bottles and feel like they are the perfect size compared to other bottles. I haven't had any issues with leaks. For camping I used them to hold cracked eggs and French toast mix. They could just hang out in the cooler , the narrow design made it easy to fit things around them, and they held up well. The lid feels secure and is easy to get on and off.

Website needs to be updated I purchased ********* bottles on line. Then a few hours later I received a text indicating that the item was out of stock. Yes, my payment was reversed back to my account. According to the website at each store, the item wasn't available. I took upon myself to drive to the various stores, and the item was there.
