## Customer Reviews

### ⭐⭐⭐⭐⭐ Outstanding and no leaks!
*by S***S on 14 September 2024*

I've used various insulated coffee mugs over the years and all of them have had the same problem - leaks. Apart from leaks, most other insulated mugs are very large considering the amount of hot or cold drink within.HydroFlask have completely changed the game with this insulted flask as it doesn't leak at all even when you turn it upside down! It also solves the size issue by being very small, more in line with the size of the contents. This also helps it to fit under the spouts of our coffee machine. The good news is that the size isn't at the expense of performance as the contents are kept hot for hours. I've found tea in particular stays hot for a long time. Travelling to a venue to watch some sport and having a hot drink for the duration is absolutely achievable.A points to bear in mind is that assembly and disassembly of the lid section can require some strength and so would not perhaps suit people with strength issues. Also, the red silicone seal needs to be fitted the correct way round (match the lid moulding with the cut outs on the seal) during reassembly as other wise this leak proof flask will leak!Personally, I think this flask is completely worth the cost for the high quality of the item. It's literally a game changer 😀

### ⭐⭐⭐⭐⭐ Highly recommend!
*by A***O on 13 June 2025*

I bought this as a gift to my husband since he's a coffee person and is always on the go. Great quality as it can keep hot beverages for a decent amount of time plus it doesn't have any leaks. My husband likes it! I would say it has good value for money as it functions how it's supposed to function.

### ⭐⭐⭐⭐⭐ Fully excellent!!
*by G***C on 15 November 2023*

It ur bringing a hot drink for later in the day, 10/10. Easy to use, clean and fully watertight when well closed so u don’t need to keep upright. Just don’t try drinking through the sip spout in the first few hours, will burn ur lip. A single purpose product that works perfectly. Looks good also very tactile.
