Reusable Coffee Tumbler with Sliding Lid & Straw | Tree Planted with Each Sale | Double Wall Insulated Keeps Drinks Hot & Cold for Hours | EcoSlurps (Black)

Love this cup! I purchased the red color as im welsh and you kinda have to buy a red cup! The cup has a really cool curved design and you can tell the quality from the weight of it. It has a slight textured surface which i like, not sure what it is but it feels great when you're holding it. I use mine for white wine in the evenings (not every evening honest!) and coffee on my commute to work. Starbucks gives money off as its a reusable cup which is really cool and i feel like im doing my bit for the environment. Something useful i would like to share when placing the lid on the cup it's worth leaving the spout open when sliding it in place then close it after. I found by doing this the cup was spill free and airtight. Really good cup i would recommend this to anyone!

Lovely design which really stands out next to more traditional travel mugs. It does keep my coffee warmish for a couple of hours but I would not guarantee much more. Great if you fill it up before leaving home or pop into Starbucks on your way to work and consume when you get there but not brilliant if you're out and about and wish to have your coffee late morning; it is rather lukewarm by then. It is mostly spill proof and the lid is really secure. Of course because of its unique design it does not fit in traditional cup holders (e.g. In the car) but that does not bother me too much. All in all, it does mostly what I expect it to, including survive the dishwasher.

Nice design, feels good to hold and straw makes it easier to drink from while driving. Some have said it doesn’t fit their car cup holder but it does just about fit mine. Can imagine it would be good for keeping beer/soft drinks cold if out camping, on the beach etc. Seems good quality, kept my coffee hot for at least 3 hours though had most of it by that time. Keeps cold drinks cold really well too especially with ice in it. Overall a pretty solid cup!

I found this cup disappointing as it completely failed to keep my cold drink cold. I had it with me in the car on a very hot day and the water was very hot and undrinkable. Not what I was expecting.

Wine, cocktails and coffee this cup is perfect!Bought this this EcoSlurps tumbler as a gift for my girlfriend. She loved them so much she asked me to get another to have a matching pair! To test how good they were at keeping drinks hot and cold I filled one tumblers with ice and the other with boiling hot was and left them on the kitchen counter for 6 hours. I wanted to see how long the ice would last, I was so impressed that upon my return the water was still warm and ice was still in the glass. The lid is excellent at trapping the heat / cold in the glass and i will be using this in the office as im always making fresh coffee as i forget to drink it when im in and out of meetings! I didnt encounter any leaking when drinking, unlike some of the other cups the fact you can slide this lid open and closed is really good for keeping drinks warm. Great cup!

Looks great, keeps coffee warm for ages however the slide lid is poor and slides forward as you're drinking. Plus its defiantly not leak-proof & difficult to clean the lid too.

Bought this cup for when I go fishing - needed something with a broad base so it didn't fall over on uneven ground, and leak-proof if it did. Well, it doesn't fall and if it does, it's not 100% leak proof, but only drips a little. Keeps contents warm for a couple of hours too. Now realised that I spend loads of time making tea at work, then leaving it to go cold before drinking, so am using the ecoslurps cup at work now and spending far less time at the kettle :) Great cup - highly recommended. Also, just found out I get money off my Costa if I use this cup. Bonus!!

The product did not have leak proof and it is too big but does keep my coffee warm for a little while.
