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

I bought this because my new bike came with Presta valves. I don’t understand why anyone would think these are better than Schrader valves when it comes to filling a tire. The fitting on the inflator is supposed to fit snugly once locked down. It does with some effort. By some I mean a lot. These valves are easily broken. Having to lock the inflator in place requires a 3rd hand to keep from bending, or breaking, the valve. It’s not the end of the world but it could be made to ensure the valve doesn’t get broken. I give the product a 4 instead of a 5 because the problem may be me.

I probably should have just returned the Presta Valved inner tubes I purchased for my old Murray Mountain bike that used Schrader valves.But I thought I'd give this tire inflator a try with my compressor.Overall I'm happy. And I would recommend it to others who bike allot more then me.

I got the one with the adapter for my road bike… there were no instructions for it. I’m pretty savvy so I figured it out, but it would have been nice to have some pointers on the use of this for the specific valve. Otherwise, love the standard connection for car tires, no longer have to hold it down on the stem, just clip and flow.

this is exactly what I needed and the gauge seems to be accurate as well. I like that you can turn off the display so you don't run the battery down.

To awkward for me to use
