Portland Design Works Shiny Object CO2 Inflator Head

This all-metal inflator looks very durable, and worked very well. Tires measured 160 PSI after use. Use one catridge for each empty tire. This unit is also great for topping off tires because the unit will shut off completely after use and unused CO2 will not leak out.

Sealed easily to presta valve stems.

Caution - the unit will freeze your hand if you don't use the leather sleeve!

Only problem was that the metal knob was loose when shipped. The knob is held on with a allen-head bolt that had was not tightened in the factory. Would have gotten five stars if the knob had been properly attached. Also, no instructions!

See Portland Designs web page for a video demonstration.

The Shiny Object is really amazing. Have used hand pumps for the past 35 years and decided to try out a CO2 inflator. Wanted it to

- Be easy to use as I am not the sharpest tool in the shed.

- Be extremely compact so it, two co2 cartridges and other basic accessories I carried could fit in an extra small under the saddle bag.

- Work well on presta valves while filling 700 x 23 road tire, and allow for easily regulated air flow along with onoff ability.

- Be Made from quality materials that would last.

- Not cause frostbite when using it.

- Make my cycling friends I showed it to go, Wow!

The Shiny Object exceeded my expectations. It is such an elegant design, simple to use, and just so darn compact. REMEMBER to double check control knob is in the off position before screwing on a cartridge.

Know Shiny Object is also available in a version that includes a leather CO2 cartridge cover, and BTDirect version I bought was just inflator. I just take off one cycling glove and use to hold cartridge. Like simplicity and figured leather cover is just one more thing for me to loose, see Not the sharpest tool in shed comment above.

Efficient, small and easy to use.

We try to carry one of these in each of our bikes under saddle bag along with a CO2 cylinder so we don't have to transfer this stuff bike to bike when we switch to a different ride.

I like the way this one feels and operates. don't think you will lose a cylinder of CO2 to the air with this one.

Great tool, would purchase another one simple and easy to use

I picked up this inflator in the hopes of reducing space in my already overloaded seat bag. It is small but better yet is that it really does a nice job. I like that it has a dial you can spin to openclose the cartridge. Feels much better built than the cheesy yellow inflator that I used to drag along.

I agree with the other reviewers, this is a great inflator. Having helped friends with inferior products, this one is far superior. Maybe a little expensive, but buy the best and be done with it.

Disclaimer haven't actually had occasion to use it yet, but how can you not be impressed with the product?! Compact, bullet-proof(comment about adjustment knob retaining screw noted and notwithstanding), elegantly simple. Not that I want a flat, but I'm eager to use it!
