I have a Lezyne and Innovations valve inflators, but have replaced both with the PDW inflator. The PDW is the easiest, quickest, and fail-safe nozzle compared to the other 2. I inflate in 2 steps. At step 1, my PDW allows me to have very slow, controlled release (twist the valve knob) to minimally inflate the inner tube, but with enough air control to see the tire is properly seeded inside, around the rim. My Lezyne and Innovations is simple push, but each push comes in full bursts. I found these bursts are more difficult to control in my step 1. Step 2 is my more robust, but still controlled, release to reach my desired PSI. There are certainly experts using Lezyne and Innovations, but I'm not one of them. I don't flat that often. But, when I do, the PDW has ridden me of all my previous fumbling and frustrations I had with the other 2 brands.
This is the only valve I've ever used that actually holds pressure after it's pierced the C02 cylinder. I've used the partial pressure after a couple of months of initial use. I use it and several friends use them as well, all have had the same good luck with these valves.
I haven't used it and hope I don't have to. The real test will be if it works when I need it or will it be unusable because I didn't use it and now the knob won't turn cuz it's gummed up with mystery funk.
It works as described. I had a flat yesterday and busted out the Shiny Object. I screwed in a CO2 and inflated the tire without the internals freezing up and with super control over the CO2 flow into the tire. There also a pressure relief hole so once you back out the cartridge it doesn't want to take off like a rocket. It slowly and safely bleeds off the excess CO2. Worth every penny.
The Shiny Object is an easy to use device that attaches to a threaded CO2 cartridge for the purpose of inflating a tire. The dial allows the user to control the amount of CO2 released instead of the all-or-none release of some similar units. It's small and easy to carry in a seat bag along with the CO2 cartridges instead of having to carry a pump along on the ride. There is no pressure gauge on the unit, however, so the user must estimate the desired pressure.
