Review: Good quality, well designed - Ease of carrying: Has a little loop for carrying while you walk. Bottle size: Small, which is what I wanted. Fits in small purse/backpack. Bottle quality: Well designed. Easy to open and drink from. (I had a small bottle that I loved for the size, but I tended to choke on the water because it had to be tipped upside down to drink from.) Easy to clean. Keeps water cool-ish in a hot car - but a note of caution here, as I only left it in the car once.. Excellent product altogether.
Review: Doesn't leak, hard to break - I don't know how many times I have dropped this thing on the sidewalk or street while walking or jogging. It doesn't even show scratches. Plus after a year of constant use (I even have it by my bedside at night), not one drop has leak out. I had to buy a 2nd one, just because I left the first one somewhere.

## Questions & Answers

**Q: Says product is made from Tritan...is this a plastic?**
A: Yes. Tritan is a BPA-free plastic — it is not manufactured with bisphenol A (BPA) or other bisphenol compounds, such as bisphenol S (BPS).
Tritan is impact-resistant — products can be used without fear of shattering.
Tritan is tough — extending the useful life of water bottles and food containers, potentially reducing waste.
Tritan has exceptional dishwasher durability — encouraging proper sanitation for greater plastic container safety.
Tritan is much lighter than glass — making it easier to handle without the fear of breaking.
Tritan has no estrogenic or androgenic activity

**Q: Is this bottle squeezable?**
A: No. It is a hard molded plastic.

**Q: Can you replace the plug?**
A: No, it is attached to the base screw top.

**Q: Where can I order a replacement top? The button on mine broke.**
A: They don't have replacements on Amazon that I found, but here's the link to the website for the store. https://www.leakproof.co.uk/collections/leak-proof-water-bottles?constraint=add-on Depending on where you're at, with shipping it could be more cost effective to just order a new bottle. They're about 5-6 UK pounds, so closer to 8 US dollars before shipping.

### ⭐⭐⭐⭐⭐ Doesn't leak, hard to break

I don't know how many times I have dropped this thing on the sidewalk or street while walking or jogging. It doesn't even show scratches.

### ⭐⭐⭐⭐ Exquisite Quality but Completely Opaque(at least the black one is)
*by C***R on March 15, 2025*

I'll add to this if I see any issues but my initial reaction is that I like it! Seemingly very high quality, the plastic has a nice dull powdery rich look to it, the pop up lid snaps shut with a little loop you can flip for extra security, and it feels European(if there is such a thing) and it does appear to be a UK company(made in china but maybe designed in the UK?). Note: the black one isn't clear enough to see the liquid and markings on the side(I took a star off for this). I needed a small 10-12oz. container for a natural medicine as recommended by The Medical Rebel that is to be drank in small amounts throughout the day. It was pretty slim pickings for a water bottle this small that needed to be opaque so no biggie that I can't see through it I just thought since it had markings on the side you'd maybe be able to look through it slightly. They should probably mention this in the description. But other than that I would recommend this! Very happy with it so far!
