    This infuser thing is great! Great for loose leaf tea! Have used it to hold my coffee too and it’s been great. I recommend!!!

    The size is great at half a litre. Perfect for iced tea when I’m out and it stays chilled while in a hot car.

    The most gorgeous flask! Love the quality and durability of Fressko products. I have literally bought over 10 of these as they make the best gift items. Just wonderful products. Highly recommend!

    I loved this product so much and I used it everyday for smoothies but unfortunately, as I went to pour hot water into it this morning to make tea, the glass shattered. Amazing product for cold beverages but not sure that it can handle heat well.

      Sorry to hear that Ramah! The glass is perfectly fine for hot / boiling water but you should take care if going from one extreme temp ( cold ) to another ( hot ) when using glass. There could have also been a hairline crack in the glass from potentially being knocked previously. Rest assured though – they are definitely suitable for hot water.

    Good Product, loved the filter, but after a small bump, the inside glass shattered after only one day.

Purchased for the ease of commuting in the winter and taking a fresh tea with me and it has done noting but leaked every time I use it! On one occasion by the time I arrived at work the whole flask had emptied into my bag. Certainly not leak proof one bit!

LOVE THIS CUP. Unfortunately Ive tried my fair share of cups, many of which baristas struggle to know where to fill but this is perfect AND fits under an Aeropress for those making coffee at home.

I was a little skeptical at first - being a long time supporter of KeepCup. But I must say, I am impressed. It's probably the only cup I have ever used that doesn't burn my hand - the outside is surprisingly cool, yet my tea / coffee is piping hot. It's also safe for those who like working with a warm drink close to your keyboard - the lid is incredibly sturdy and practically impossible to open without brute force. I received this cup as a gift, but if I did know anyone who was in need of a reusable takeaway cup, I think I would give them one of these.
