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.
Great product, lightweight, user friendly, It's nice being able to regulate the air flow. This is just one of those products that does exactly what it was designed to do and does it well.
Finally had to use this in anger the weekend and I was pleasantly surprised. More controllable than I had thought it would be. THe valve is smooth and you will be able to let in just a little or a lot with ease. Stores in a tiny space. My fizik bag easily holds this, two cylinders (16grams), a tube, multitool, and spoke wrench. even if I get picky I cant find any issue with this at all.
I received two back to back flat tires in the beginning of an 75 mile ride to Piermont and back earlier this week. This tool definitely came in handy. It is compact and easily fits in a saddle pouch or jersey pocket. It is made of quality materials and I love the fact that you can vary how much CO2 is being released via the vale. The changed tires were inflated in seconds and I was on my may. Funny enough, one of my riding buddies suffered a flat on the way back (on the same trip). It was my first time using the tool and I had the opportunity to use it 3 times in one day. All in all, well worth the money.
