Update: My sensors have deteriorated. Both. Will not return to zero. This is after maybe 3 uses in a year. Although the hoses are still good. My words about valves still stand. Don't twist them and you'll be fine. High quality tubing material. I used to have a cheap kit and the hoses would dry out and crack. This will take a while. Overall a decent set. Just remember that you don't have to turn the valves when opening/closing. If you do this, you will wear out the valve seats. This applies to all gauge sets. They are excellent tools and should be treated accordingly.
