AZUNO Bike Tire Inflator with Pressure Gauge - Bicycle Presta and Schrader Air Compressor Tool

I dislike presta valves anyway, largely because I've yet to find a pump that makes it easy to pump them up, including this one. Really, this entire unit is overkill.Think about how to use this: Take the cap off your valve and unscrew it a bit. Put this connector over the valve and pop the little securing level up. It doesn't secure it to the valve at all. Which means, you have to hold it, pretty tightly down on the valve. Meanwhile, with your "free hand" you have to grasp the trigger to trigger to air to enter the unit. Even IF you're successful at all that (holding the valve tightly to your bike tire with one hand and hold the trigger with the other), it's unlikely you can even SEE the gauge because it's twisted sideways because the darn thing is so big, and even IF you can, it's horribly innacurate either because it just is, or because I can't get a good connection on the valve because the thing won't actually stay on the valve by itself.Suffice it to say, I'm STILL looking for a presta valve pump that will actually stay on the valve without my having to hold it down tightly.

(at least that's why im buying this and 1st to try).Frist thing to notice is the Presta nozzle is in great quality, I was hesitated when I saw the picture before I buy, it's made of plastic and how long does it last? It is made of plastic, but very quality and solid when you have it in your hand. I push the nozzle all the way thro and push the level to lock it. Push the level on the gauge and it start to inflate. I notice the Presta Schrader nozzle has lower PSI limit than the gauge, 160 on Presta and 200 on the gauge. Manufacuture explained that the gauge is not only for bikes but also for commercial vehciles, they included accessories to do that. 160 PSI is more than enough for most bikes so the seller cleared my question. The inflation is effortless compare to the pump, you do not get a faster inflation speed due to the size of the pipe, probably a bit faster because I need to rest if I pump all my tires, compressor does not.The digital gauge is clear and bright, I like the LED flash light on the back which is very handy when you work in dark garage in the evening.I also test other accessories, 2 coupler for compresor which I only need 1, dual head air chuck for trucks is very solid with rubber grip, generous Teflon tape. OVerall I give 5 star since no problem so far and quality is good, will update in the future if anything chages.

The device comes with a Schrader clip on style head attached and a Schrader / Presta combo head separate. I removed the Schrader clip on and attached the included combo head. They even included some Teflon tape to make the connection with. So far so good. I've filled Presta tires to 110 PSI, car, truck, and trailer tires without issue. I've gone back and checked it against several different gauges I have as well as the TPI system on my car. All read with 0.5 PSI of each other which is a 1 PSI range of accuracy. More than meets my needs.

A digital air gauge that easily switches from bike (presta and schrader) to car (both stick and clip on ends). The accuracy and the ability to easily raise or lower air pressure with the lever or button (release) while monitoring pressure gives me a new level of control with my pancake air compressor previously bought for tools.When inflating tubeless tires for the first time, the ability to quickly fill (without the presta valve insert), release, insert the valve, and then reinflate to pressure is just a lot easier with a tool like this.Getting every tire (or ball) to the correct pressure is satisfying, especially if you are a bit detailed oriented. Remember that the temperature of the air matters when adjusting pressure.

I had several products from amazon, this is by far the best one I have got.First, the presta schrader dual head chuck is very solid build, it grad much easier and faster with no leak at all compare to my last set bought from amazon (works but do a margin job). I pushed the chuck all the way through with confidence and push the level opposite direction, normally with other chucks you have to push/pull few times before you get it right, with this it makes it so simple (if you used similiar different bike pump chucks before you know what i am saying). After I finish my bikes, i start check my RV and Jeep, both the 90 degree extender and dual head air chuck works well. I like the dual head very well because it is such a quality piece, you can tell that from the weight itself, the rubber grip makes it very comfortable to use.I can tell the gauge is accurate since I got same return from the gauge and my Jeep. The back light is bright enough, the LED flash light can be convenient feature if you forgot to carry one.The customer service is also prompt, I got a thank you email after I purcahsed, with the manual attached, question was answered responsive.Overall I am very happy about the experience I have. Good work!

This is a must if you have a compressor and don't to spend money at the gas station airing up your tires. Very simple to put together, no leaks from any part of the unit when not in operation and quick read outs as you fill the tire. With the changing temps in the north east, I am always trying to keep my tires at the right level in order to save tread life, and this tool makes it super easy and quick to do it. Everything you need is included, even the plumbers tape and two different size compressor fittings. Very happy to have this in the tool box.
