Dishwasher safe now leaks
No leak and dishwasher safe baught my first flex straw with my first hydro flask in 2023 .Can't fault it best drinks bottle I have ever had still going strong but needed another because I use it constant and it never gets washed so decided to purchase another and the colour moonshine I wanted wasn't available with the straw lid so happy to purchase another .A bit expensive way if doing it but I know its going to be going strong in years to come .

Nice quality, can be hard to clean
Much nicer to use than just a no-lid hydro flask. However after about a year the scale build up in hard to reach places has made it slightly annoying to clean. I had to cut the plastic straw down a few times to get the size right, but definitely better than no lid!

Easy to fit and makes the flask even more user friendly.

Lovely product
Perfect size for my 621ml water bottle. The straw is easy to adjust/cut to size. No spill at all as the cap is totally sealed. Love this purchase.

Does it's job
I bought this for a Primark metal bottle as I needed the sip lid and it does what it says. The best thing is that it fits any standard lid bottle from any shop.

Good idea, not the best to use
Great delivery and price. Weird to use... you almost have to press down to make sure the straw opens whilst drinking
