Works Great
Works great and I really like that it threads onto the presta stem especially when seating tubeless tires and you need all the air pressure you can get going into the tire. Quick release works as described.

How did I live without this?
I purchased these to work with my Jaco inflator. I didn't really need two, but I'm sure I'll find a use for the second one. In any case, it was worth the price just for one.I have too many bikes, including two recumbent trikes with 20" wheels. The trikes (and most of the bikes) have Presta valves. Because the trike wheels are small, there's not much room to work with. In the past, I used a Presta-to-Schrader adaptor to check and fill the tires. This meant that I had to remove the dust cap, unscrew the valve, attach the adapter, and then check / fill the tires.Since this is a right-angle chuck, it locks on to the valve, making it fast and easy to inflate the tires. It also eliminates the need to attach and remove the Schrader adapter on each tire.I have seen other review stating that it is hard to get the chuck to lock onto the valves. I used this on several bikes (and a car) with no issues at all. It does take a little practice to switch the valve from the "P" to the "S" setting, but it really couldn't be much simpler.Now I just need to find a use for that second chuck...

Like the idea, but hard to use
I read about this tool, was impressed that it appeared well-built and handled both Schrader and Presta valves (I mostly cared about Presta for my bike and filling/seating tubeless tires). I found it frustrating that I really only wanted/needed one chuck, but the offer was for two chucks, so it was that or nothing. Consequently, the price was about double what I felt I should have to pay. But for a great product, I would do it (and maybe share the other with a friend)!I found the chuck a bit challenging to use. Maybe if there were instructions readily available, I would know the tricks on how to use it better. (The manufacturer pointed me to the video on the product page, though it seems more promotional than instructional in nature. Though it did reinforce the idea of threading the chuck onto the valve after locking the sleeve.)* Switching between Schrader and Presta is awkward and hard on my fingers. It seems I need to hold a narrow band of the barrel to keep it from rotating, while rotating the outer barrel against the inner barrel to switch S to P. The manufacturer suggested that if I extend/lock the blue sleeve, it makes it easier to grip the inner barrel. I tried that and it helped some, but the polished ridges are still not easy to grip; I think a knurled surface would help greatly. Or maybe a button or something I could press to lock the inner barrel in place as I turn the blue sleeve.* locking on to my Presta valve doesn't feel secure at all. After placing on the valve and sliding the outer barrel outward toward the valve, it kind of locks on, but not solidly and it seemed to leak air. After contacting the manufacturer, he suggested I try locking it then threading it on; that seemed to be more secure, though I haven't tried it under pressure yet.)* it would be helpful if the chuck could swivel at the 90-degree bend. Given that it gets threaded onto the end of a hose, and hoses don't naturally swivel, it made it awkward to get the chuck in the position/orientation I needed it to secure it to the stem.If I missed some key instructions and it is really much easier to use than what I experienced, I would be glad to know of them (the manufacturer suggested some tips when I contacted them). I like the flexibility of being able to do Schrader or Presta, but for someone buying this primarily to use on Presta valves, I might be more inclined to recommend a bike-pump-style combination inflator and chuck. My inflator came with a head that works passably (not well) on Schrader valves, so my motivation was all about using it on bike tire Presta valves.When I contacted the manufacturer with questions and concerns, a gentleman responded to me very graciously with helpful comments and ideas. A+ for support!

tons of air flow
I purchased this and replaced the Schrader attachment on an old air inflator by using a 3 foot PVC hose and some quick connects. A bit overkill but it was all I had as spares.The fitting does leak air as you're attaching it onto a Presta valve, however since you're likely filling up a tire anyway, then I don't see this as a big deal. The air flow through this fitting is phenomenal. I went from 5psi to 60psi in a few seconds on my 26" home-brew tubeless tires.BE SURE TO HAVE YOUR OUTPUT REGULATOR SET ACCORDINGLY otherwise you're likely to blow the tire off the rim. It's also just good practice for safety.The quick release of the fitting is pretty sweet with minimal to no air loss as far I can tell. You can hear air escaping on disconnect, but it's likely from your hoses. Attaching a pressure gauge to the tire shows no discernible losses.I'll update this review as time goes on as I plan to use this long term.

Does not work, don't buy this
I have been using a JACO analog tire pressure gauge for years with not problems. So, when I saw the digital 200 PSIG air gauge and bike tire adaptors at such a great price, I purchased them.FRUSTRATION, FRUSTRATION and more FRUSTRATION for the get-go. First the sealing O-ring on the end of the braded hose will only seal the original Shrader fill/clip. Second the really cool chrome and blue air chucks do not grip the bike tube Pristas valves thigh enough to hold air. It's an air leak mess, impossible to fill modern bicycle tubes or tubeless tires. The sealing O-ring on the braded hose does not seal the chrome/blue P/S air chucks.Good idea but poor design and quality control. JACO you should have sent a few of these out to your valued customers to do a little testing before you gave them to the general public.P.S. I'm keeping the digital air gauge, great product, it works flawlessly on automotive tires. And with a Prestia to Shrader screw on adaptor from my local bike shop the digital air gauge/fill works great topping off my road bike tires.

Works great for Schrader
Item works great for Schrader but feels a little loose for presta. Definitely get what you pay for because the bike shop grade ones cost 3x as much.
