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!

Makes flask more user friendly
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

The smell of the red silicone
For those who are sensitive to smells this cap is not a good choice. It has quite a strong smell from the red silicone. I cleaned it many times and left it outside, anyway it smells.

Worth the money
Love it, great attention to detail. It comes with two straws, you cut it to decide the length so it works for all bottles that fit the lid shape. The red tab at the bottom can be used to hang the cap on the side of the bottle so its easier to fill up without pulling the entire straw out.

Good lid; Does not leak
My original purchase was a sport lid for my hydroflask, which leaked on a regular basis. So far, This lid seals great when closed and opens with ease. It does exactly what I bought it to do.
