Review on Colby Valve XL Emergency Stem by Jeremy Jackz

I ordered smaller valves not knowing my tire has a larger puncture. The smaller valve could slide right in, bypassing the beautiful brass device. I modified and sealed it, but it took a lot of work and rough handling. Don't worry, their rubber and brass held up to anything I threw at them. I was able to seal the wrong size valve but I'm not sure it will hold up so I ordered this to replace. These valves are REALLY easy to install and USE. Also, I'm an engineer, so I enjoy watching them. They are made of solid brass, look handmade and convey a high-quality overall impression. If Rolls Royce made valve stems this would be the one.
