I'm one of those people that prefers coffee in a takeaway cup rather than a ceramic one. I'm not a raving greenie but I would prefer not to contribute to unnecessary waste where possible. I mainly use my keepcup at home when making coffee and it works really well. It's a standard size, it's easy to clean (it all comes apart) and it looks appealing. It's not 'insulated' but it keeps the coffee at least as hot as a take away cup would, and because of the lid, I think it keeps my coffee hotter longer than a ceramic cup does. I use mine daily and it's held up perfectly well for over a year, so durability isn't a concern at all. Also worth noting is that it doesn't give off any tastes.
Durable, Easy to clean, Doesn't taste.

I'm so in love with KeepCup that I'm ordering 500 of them with our business logo on them to use as marketing tools!

I was given one for my birthday by my sister when I got my Nespresso machine so I could make my own take-away coffee...its the only cup I use now!

The lid seals tightly. The sipper cover clips in nicely. They come in a range of colour combinations. They go in the dishwasher. Very durable. Standardized sizes make ordering cafe coffee easy.

It's just a bloody good product!
Everything.
My husband keeps using it & leaving it in his car...
