Make sure you don’t drop it

The cap is so delicate a small drop could break the lid of the bottle. Performance wise it is amazing.


The silicon seal pops out easily and gets lost. I have 2 ball players and both of the seals on their water jugs are missing. As a result, the water jugs leak so can't be pre-filled. You can only fill the jug just before using, as it would spill otherwise. Sadly, you can't even find a replacement seal to purchase. This is a known issue, so one would think selling the replacement seals would be a no-brainer. Looks cute, but basically junk. Don't waste your money.

Handle easily broken by 10 year old

These jugs are great for baseball. My 10 year old son was so excited when we bought him one in red - his team colours. But it didn't even make it through one tournament. He broke the handle on his jug the second time he used it. Not sure it is worth the money. As a team, we will be sourcing other options.

Mold issue

Great product but the silicone seal seems to mold easily and can't be removed even with bleach and scrubbing. It’s been using for around 6month, it started to get mold inside silicon. Not sure if I keep using it, hope that I can new silicon seal for the replace.

Great we have 2!!

We have had 3 (1 Black, 1 Red, & 1 Blue) of these 64oz for about 3 years now and love them! They are cleaned, refilled with filtered water, and stored in the fridge so they can grab and go with them 3-4x weekly TKD & Caperioa classes! They work as great today, no leaks, as they day we bought them! Water stays cold and has ice even hours later! No plastic taste! My ONLY down side to them-the handles need a squishy type cover-hurts my hands carrying them into tournaments. (But I LOVE you can carry 2 back to back handles up in one hand)! EXCELLENT PRODUCT! TYSM!

Great Bottle except...

I’ve bought this water bottle several times. It is the perfect size, it’s easy to carry, and it keeps my water cold without sweating all over everything. My only complaint is with the rubber ring on the inside. It grows mold even if I take it out to clean it and let it dry frequently. Is there a way to replace the rubber ring?

Missing rubber stopper

Purchased it and didn't use it right away. When finally went to use it found out the rubber stopper piece that keeps water from leaking out is missing. Nothing there just a hole.

Easy Visability

This is easy to find no matter where you are. Great size and keeps the liquids where they belong. The finish on the bottle is great for using a sharpie for names etc. Awesome!

Love water bottle, but cap keeps breaking

My daughter loves these water bottles but the caps keeps breaking. The cap just broke on her third water bottle. We only used this bottle twice. Can't keep replacing these bottles at this price.

Bad gasket

I have purchased 2 of these jugs and both get black spots on the gasket. For as much as these jugs cost, you would think replacement gaskets would be available.
