Shiny Object CO2 Inflator Head

the best i have ever owned small design and easy to use, you have full control of this inflator, solid and very light, a must have on your rides.

i've been using these since 2013. in that time i've had 2 warranty issues which PDW replaced or repaired them. one time the center pin blew out and thus wouldn't puncture the cartridge. the second one was the dial would just spin and not move the stem. so in 6 yrs 2 failures in 50k miles. it doesn't seem that unreasonable, but if you've found a more reliable one, please share it. i love being able to slowly regulate the flow and partially inflate a tire and make sure it's seated and check for add'l leaks rather than blowing the load in one go. i also don't need the full 16g cartridge for 25mm tires, so saving a bit in the cartridge and throwing it in a jersey pocket with some extra is nice. if it had a pressure gauge, i'd give it another star.

This shiny object works great, it is so easy to regulate the flow and it will hold the leftover CO2 for days. Its small and light. You can't ask for anything more.

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.

I carry a very tiny saddlebag, and this fits perfectly with a tire, cartridge, and levers.

This was a gift to replace a lost/stolen one and my son likes it very much.

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.

It's great to have such a small, functional pump to carry. I had no idea pumps could be this small until it showed up at my door. Very nice pump and as always Western Bikeworks delivered it very quickly.

I never thought I needed one until I needed one

Works great when it does, I like the onoff control of CO2 flow. But after a few uses the rubber O seal that wraps around the stem literally blew up.

I love being able to accurate the amount of air going into the tube so that I can more precisely inflate the tube. Would recommend for anyone

I Purchased this inflator after using a friend �s during a ride with the puncture. It�s solid and easy to use.

less than a week after receiving it, I had a flat. Product worked perfectly and allowed me to gently release C02 into the tire to seat the bead.

Compact inflator, easy to use, well made. I like the ability to control the flow much better than cheaper models that are all or nothing.

I found this inflator head super handy out on the road. I like that I can control the flow with ease. Well-built.

Don't buy this!!! the rubber seal inside blew out the first time I used it. You can no longer use this once the rubber is broken.

Great lightweight inflator, super easy to use.

Used this yesterday for a flat. Works great. Not much else to say!
