    I love this product but from a not very hard put down on the ground in a bag, it shattered.

    This is hands down my favourite bottle, as it makes it very easy to stay hydrated even in Winter and is great for teas and tisanes. I have had it for almost a year and the bottle and filter themselves look like new; the only disadvantage is that the bamboo has started showing water damage. It is only washed by hand and never taken on the go, so I assume with time the seal/glue between the plastic cap and the bamboo got a bit loose and water gets in. Overall really happy with it.

    Loved it when I initially used it; however, after just two weeks, the glass inside broke (only lemon infused cold water inside) while it was just sitting on top of the table. I had to throw it away because I don’t want to drink broken glass. I’m sad it broke. Now looking for a replacement.

    Amazing product that is very aesthetically pleasing. I have accidentally damaged my lid and their customer service was great, they back their quality product.

    I use this flask during the day for water and lemon, and then in the evening for my tea. Really sturdy, so much better quality than lots of others on the market and it has many uses.

Fav coffee cup. Seriously it keeps my coffee so hot I can't us it with the lid on if I want to have my coffee after brewing it. 100% recommended

1 month ago

Very impressed with this cup, I've had it for a couple of months now and loving it. The rubber base is a nice touch that I didn't know I wanted. The lid is far superior to other reusable coffee cups I've used, I can fill it up place it in my bag for later and it doesn't spill a drop. And it holds heat very well!

My only complaint, which isn't really a complaint but a minor inconvenience, is that it is 1mm to small and my aeropress just fits in the cup and gets stuck if I push down too hard. I do have the small version on this cup so maybe the larger one doesn't have this issue. But apart from decanting directly into the cup from an aeropress, this is a fantastic cup for every other use.

When I bought my cup, there were no local stockist so I had to order from an overseas website that offered shipping to my country. Had to wait some 2 months for it to arrive but it's worth it! The BEST cup ever in all ways a cup could ever be and I have used quite a few of these reusable ones.
