Portland Design Works Shiny Object CO2 Inflator Head

Works great, small, and light. Much better than the Lezyne POS that failed when I needed it.

Two needs for this sort of product bc 99% of the time you dont need it - that it works and its small. This product wins on both criteria.

I've tried a bunch of these over the years. Some look good, but break quickly. This one is small, simple and tough. It works when you need it.

Used only once and it worked great. Fits really well in my under-the-seat bag.

Solid design, durable and no problem inflating my tire.

If you use CO2, this is a great device - compact and light weight.

This is simple, small and reliable. Well designed!

Having control of air flow is what it is about! Slow or fast inflation is crucial, and this Shiny object allows this.

This Portland Design Works inflator is so easy to use it makes me want to have a flat tire!

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.

This can be throttled to a minimal flow for gentle control of inflation.

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.

bought this in Jan 2015 - Used 3 times. First use - worked as advertised. Second use - had difficulty with turn knob and burned 2 co2 cartridges to inflate tire. rd use - knob kept turning and never disbursed CO2 - never got my tire inflated. I went through another 2 cartridges and still had a mostly flat tire. Luckly a buddy had another inflator which worked by twisting the cartridge to engage rather than a knob which just spun (open or closed).

I was looking for a design that would fit my road bike's presta and my spouse's and daughter's schrader valves and this one fit the bill.

It's sturdy, lightweight and compact. It is easy to control the airflow with the knob.

I bought this because my previous inflator did not work for me. I normally have used a frame pump for my tubed tires, for years and years. My newest bike, I made the transition to tubeless tires. Also, I didnt feel a frame pump was proper for use on this bike, so I switched to CO2. I threw an o,d inflator that Id had for years into my seatbag. First time I needed it, it didnt work. I ordered the Shiny Object head as soon as I got home, mostly because of the reviews I read on BTD, and they had a great sale price. Ive only needed to use it once so far, but it was so easy and worked perfectly. I am very happy with this purchase. Thanks BTD and PDW.

This is a really good, useful product.

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.

Not unlike other all metal inflators this works good but gets so cold that I couldn't turn it off or get it off my tire even with gloves on

With the Shiny object you can easily dial in the amount of co2 you want to put into a tire. Great for checking to make sure you don't have any tube pinched under the bead. Then let it rip and fill the tire.
