Well, all the Wistio valves are very good made and have a very good quality, but not every one fits in my rims 🙁 . But im shure that they are good and durable as the others. For me (beacouse of my rims) the red one that is entire out off aluminium and the blue one are the ones that work. and for my other bike just the squared ones works! The quality off the product and material are very good and they never let a bit of sealent out never.
