Honestly, this feels a little gimmicky - it's a nice novelty, but I don't think it's very practical on a permanent basis.It comes squished down, and you just twist it sideways and up and the silicone body opens up to full height.It's a clever thing, but I've noticed that the smell of whatever is in it tends to linger, even past washing. For example, I made a pumpkin spice coffee, and even after washing it, there was a slight coffee smell that lingered inside, and I don't like that. That's likely the silicone.But there's no denying that if you use reusable coffee cups and you need to be able to squish it down into a smaller coffee cup size, this is a good way to go. It's clever, definitely; it's also expensive at £19.95 - I've given it 4 stars because it's a nice thing if this is something you need. But as cups go, it's more like a 3.

The media could not be loaded.  If you’re looking for a space saving coffee cup then this is great but how much room does your coffee cup take up!? Mine isn’t that big that it creates a problem. At risk of sounding too miserable I should say that this is a novel way of drinking coffee! However for just under £20.00 this is a pricey cup of coffee! Yes, it’s reusable but that’s still expensive for a rubber and plastic cup.The rubber bottom can be twisted and stuffed under the plastic rim then held in place with the elastic band. The cup can be used with or without the lid. There’s a sippy hole for slower drinkers like myself! Can be used for hot or cold drinks - careful when handling very hot drinks.Cup fits neatly in a bag when folded and it’s a good fit for a car drinks holder when filled.It’s still £20.00 though!!!

Very good idea as nobody wants carry a massive to go mug as you can just fold it after using it with the band around it to keep it folded. The downside is the design of the lid it self was very difficult to get sip of coffee without dripping from when drinking it and the other major issue for me is the lid would have been better if it was screwed in rather than push it down to close it but really it just never was and locked in just pushed a little down which could pop open every time i was taking a sip and that didn't make me feel comfortable. If these issues was sorted out then i think it is a brilliant idea, i hope my review has been helpful

Foldable- great idea, takes a little space.Silicone/Rubber cup- not as sturdy as I thought it would be, also once hot drink inside the silicone mug is made from become very soft so you have to be careful not to apply any force/squeeze so your drink does not go out from the cup.It leaks a bit as well so overall not impressed and would not recommend.

This cup was delivered quickly. It is easy to use and fold/unfold. It does the job well and I guess it works, it holds in heat well and it has a safe clicky bit where you can close or open to drink out of.I know this is supposed to be a travel mug and it can fold, however it is not sturdy enough and I am constantly worried when I am using it if I am going to spill. A little bit sturdier and I would give it 5*.

I found this cup really easy to collapse and the elasticated strap keeps it closed well. The cup is the equivalent size to a standard mug, or a small at coffee shops.The lid has an opening with a lid to shut off to prevent spillages when not drinking. As it is collapsible, the walls are very thin so not a lot of insulation otherwise I would have given this 5 stars.

This folds up very compactly with a twisting motion, and does make it quite easy to carry a renewable cup with you. You do need a bit of care in use, however, as the silicone can get a little warm if you pour freshly boiled water into the mug, and, it's not solid - an inadvertent squeeze could have hot coffee leaking out on you.
