Really useful. They do indeed change colour. Come with straws, they hold a good amount too, over a pint for sure

The kids and adults love these well made the kids love the change of colour when cold drinks are in and that thay can change to a diffrent lid and straw to be diffrent took them abroad came veary handy didn’t brake at all after checking luggage I kept getting ask where do you get them from love them

Colour changing isn't that great and the lids don't match the cup colour wise.But they are great for holiday when we go to all inclusive, so you don't have to use the small cups you are given.

These cups were definitely a surprise. For the price I paid I did assume that they wouldn’t be as good quality as they are but extremely study cups, the lids for great and although not all of them seemed to change colour all the time unless a lot of ice was in the cup they did change colours and washed well.

These quickly became a favourite in our house, for both the size and the ease of use without spillages. We've all been using them and found we're actually drinking more as a result too.

1. One arrived cracked- wish I’d planned ahead2. Colour change works well. Ice really helps!3. Yes, they are dishwasher proof. Hurrah! Washed several times, colour change still works.

I love these cups.Water must be very cold for them to change colour.I use my cricut machine to add patterns on them and they always look amazing.Only issue is, they give you one cleaner for 5 cups, so I had to buy more cleaners.
