Portland Design Works Shiny Object CO2 Inflator Head

Works great! You can really control the air release. No more wasted cartridges.

This is a really good inflator. The valve on the top really lets one regulate the flow of the CO2 gas into the tube, and if for some reason it's leaking around the valve you can cut off the flow quickly.

This is far and away the best CO2 inflator I've used. Extremely light and compact, yet also extremely well-designed and durable. The wheel allows you to reliably control the onslaught of CO2 into your tire perfectly, and the simple T design positions the cartridge in a way that's easy to hold and get the inflator on and off the valve stem without a fuss. Can't ask for anything more.

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.

The product is advertised as pretty, compact, durable, and easy to use. Personally, I care less how pretty it is. Compact is somewhat important, but durability and ease of use are the key requirements. The first time I used it I thought it was easy to use. But the second time I used it (fixing my daughter's flat) it came apart and I have not been able to put it together. So save your money and get something less pretty that holds up to the demands of pressurizing a tire.

I sued this inflator for the first time this weekend. I flatted out in a race, pulled this unit out and was back in the race in less than 30 seconds.

I got these to replace a co2 inflator that failed after years of service. I prefer an inflator that screws securely the presta Valve. But after using this one. It's not bad at all. Just hold on to valve and open the valve. Couldn't be simpler. I like the adjustable valve. You can just give a small shot to locate puncture it tube without dumping the co2 charge. With this co2 inflator I found it easier to locate, patch , replace the tube on one 16 g co2. It took a few times for me. But I can patch a tube now on one co2 in under 3 min.

I have a lot of Bikes and like to carry an inflator pre-packed on every bike so I don't have to change packs as I grab another bike. This is the best one I've found. The quality is 2nd to none and with BTD prices is an outstanding value. I Love that you can regulate the flow of CO2 to avoid freezing the valve or tube. It's nice and light too for you weight weenies. Get one you'll never look back.

I found this inflator head to work as advertised.

Great!!

Rated 4 star because I haven't had to use it yet...touch wood. But it is exactly as described online.

Nice quality inflator head.

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.

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.

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.

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.

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!

Efficient, small and easy to use.

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!
