Yes!
I love this mug, I had the bigger version but this one is much easier to carry around. Good size and fits my car and pram. Well insulated. The only thing is that if you knock it down the lid may pop open and then it spills everywhere. It is easy to clean, all parts come apart.

Impressive
Excellent quality. Ergonomically designed, even though it might not look it at first glance. Easy to clean and importantly keeps water cold all day. No regrets, other than I should have bought one earlier.

Great size!
Quality, and the size isn’t as massive as a lot of other options

Hard wearing great quality travel cup.
Great quality. Was a bit on the expensive side when I bought it at £39.99 - but it's now less than £30 and at that price it's a steal. Keeps cold drinks cold for most of the day, in my experience hot drinks tend to cool down after 4-5 hours - but it's an insulated cup with a straw, not a sealed flask, so it's to be expected. I've knocked it over quite a few times and never had any spillages, that said it's always been half full or less. Been using it daily for 6 months now, no signs of wear and tear - looks the same as it did on day 1. I tend to hand wash it but it has been in the dishwasher many times with no issues. My only gripe is that it doesn't fit into every cars cup holders - my Volkswagen Touran it's not a problem, but in my C3 Picasso I have to use the cup holder on my daughters car seat, so if you do have a smaller car, or a car with a smaller cup holder that may be a problem for you. Dropping one star for that, but only because you can't drop half stars! It's definitely a 4.5 star cup!

Hand for use when breastfeeding
I own a few different hydroflask models but bought this one for accompanying me during breastfeeding as it doesn’t require opening and closing, handy when you’ve only got one hand free. When I add a few ice cubes it stays cold for hours. It also holds loads so last me ages. I didn’t go for the biggest model, and glad I didn’t as I think it would’ve been very heavy to hold. Also very easy to clean. Very happy so far.

Fashionable and durable
First off, the insulation is incredible - my drink stays cold for ages. The size is perfect for keeping me hydrated throughout the day without constant refills. I especially appreciate the no condensation on the outside, and it's held up great despite daily use. The handle is comfortable and makes it easy to carry, even when full. It is also super easy to clean.
