AZUNO Digital Bicycle Tire Inflator Gauge, Auto-Select Presta & Schrader

I am able to use this on my bicycle and motor vehicles, except my motorcycle. Beats switching back and forth between an air gauge, air chuck and manual bleeding of air from the tires. Seems well put together; solid, not flimsy. Guage is very easy to read. As others have noted, can be a little tricky to fit over a presta valve, but a good push and it locks tight over the valve, although it might take two or three attempts. Cannot maneuver the hose on the tire valve of motorcycle due to tight space of valve behind the wheel spokes, hence four stars foe "ease of use," however, perhaps a horizontal valve would solve that problem. Will install such valves at next tire change and see how it works. Overall, very pleased with the product. A good value IMHO.

Updated Review December 2020: After my initial review, which you can read below, I was contacted by Azuno via email. They wanted to make it right in two ways. First they were taking details from my review to help make the product better, which is how it should be, so I appreciate that. Second, they offered to refund my purchase or send me a newer product to better fill my needs. (There was a third option, but I can't remember it at the moment.) I took the newer product. I like to see a company take accountability for a bad product and then take steps to make it better. Original Review October 2020 was two stars: Got this Azuno bike tire inflator to inflate my road bicycle tires. First time I used it, it worked fine although it does leak, but it wasn’t so bad that I couldn’t accomplish what I needed to do. Temp went down to the 40s so I figured I should check all vehicle tires. Did okay on both cars, but it did leak more than the first time. Both vehicles are at 33 psi, so not too high. My bicycle though, is 100 to 130 psi and I usually go 115 psi. I got it on the presto valve., which is always way more difficult than it should be. Squeezed the lever to get the air to flow and the hose on the presto adapter split. I took the that assembly apart and cut the split section off then reassembled it. Stuck it back on the valve and pulled the lever and “pop” it went again. It’s also very difficult to remove. The garage works good though, but it does leak a little which I figure it will inevitably get worse. I should’ve known better since the description is very poorly written, but then again so are a lot of the reviews, LOL!

Good quality for a light use inflator. Not a pro piece of gear, but good enough for most users. The "universal" Schrader/Presta adapter is good for Schrader valves, and passable for Presta valves. Hoses and hardware are good quality, gauge easy to read, reasonably well-calibrated (~ within 2-3 psig). At 1/5 the cost of the very nice Park inflator, I can live with it. I might buy a Presta-only head to improve it. UPDATE: 3.5 years in, still works very well, quite accurate and easy to use.

Wow this thing works better than advertised. It fills up your Presta valves bike tires with ease. Not only that I used took off the Bike hose attachement and used the brass schrader valve attachment. The brass fitting attaches to Schrader valve stems without leaking. It has a squeeze trigger that locks onto the schrader valve to hold it in place. I used the brass schrader valve attachement to fill up the car tires on the wife's Rogue. I love how it shows the psi as you leg go of the trigger and has a relief valve to let air out if you over inflate the tire. This bad boy is just like what the professional tire shops use.

I've always hated having to put the little adapters on the presta tyres. This was easy to clamp directly onto the presta tyre. The big PSI reading is nice. The unit I received has a faulty inlet valve. Once the inner tube pressure reaches 50psi the valve fails to fully close and leaks to allow the pressure to increase at about 1psi per second. I like my tires at about 85 so I've just been filling to 80, waiting as it increases to 90, then quickly popping the clamp off the presta tyre. August 9, 2021 update: Wondering if there is any warranty. The unit just completely failed. While filing a tyre to 100psi something internal blew and it doesn't hold pressure at all. I can't tell if it's the button meant to let pressure out, it seem to feel like the air is coming from there but also the edges of the hand grip. September 9, 2021 update: I didn't hear back anything about a warranty on the unit so I decided to try to make it work. I wrapped my index finger and thumb around the handle top below the gauge where the air was leaking out. It was impossible to get a good seal with the hose running up the back. The high PSI air went ripping by my index finger leaving me a very nasty 2nd degree burn style blister. Its now in the landfill.

I have started to maintain my own bicycle lately. This included swapping road and gravel tires are couple times a year. I had need of a presta based tool to work with my pancake air compressor. I saw this kit, and it seems like it would do the trick at a reasonable cost. Honestly, I found it a little difficult to work with. The nozzle did not fit as securely as I would have expected. The pressure reading on the digital display was surprisingly slow to update. In hindsight, maybe an analog dial would have been better. This kit has all you would need, fittings an all. However, I'm just disappointed in the gauge and the nozzle itself. Because of this, I would not recommend to others. Would I recommend to others: No Would I purchase this again: No

Works well

Purchased this unit for use with the handcycle i purchased this summer. Presta valves were new to me so there was a learning curve but the device performed swimmingly once I learned how to use it properly. After approximately 5 months - the hose connected to the Presta valve chuck split. I managed an improvised repair and the other end split too. I emailed AzunoTools on Sunday, had a response in under 24 hours telling me to expect a shipment to arrive Thursday (tomorrow). An entire replacement unit (all I needed was the 2nd hose & chuck) was delivered today. I'm more than impressed with this product And company :)

Tres bon

Works good on all my bikes except the road bike. Though it says it's good for 100psi the nozzle seems to start leaking around then. If your desired pressure is below that, should be good enough.
