TYH Supplies Tire Air Pressure Gun Inflator Gauge with Chuck, PSI/BAR Dual Measurement up to 174 PSI, 1/4-inch Flexible Hose, Accessory Kit, Schrader to Presta Valve Adapter, 20 Valve Caps

Can't beat it for $10. As another reviewer said, if you're getting this to use for bike tires with presta valves, you first open your presta valve, screw on the brass adapter, then attach air gun to it by simply using the clip to grip on to it. Works perfectly and is SO much easier for mounting mountain bike tubeless tires! Don't know if the gauge​ is totally spot on, but it's close enough and I can double-check with my floor pump later.

I bought the TYH inflator to allow my compressor to fill bike tires with presta valves. Two presta adaptors were included with the product with no instructions, but with some trial and error, I got tires inflated. The process is as follows: 1) Loosen the presta valve seating ring. 2) Screw the brass presta adaptor onto the presta valve. 3) Clip the TYH inflator head onto the brass adaptor. 4) Inflate the tire. On my first attempt, air leaked from the side of the inflator head. I decided to use both hands on my second attempt, one on the inflator trigger and one on the inflator head adjusting the head to see if the air leak could be diminished. Sure enough, the air leak was much less. I expect the inflator I got had a defect because the pressure gauge would not hold the reading after I released the trigger. TYH even includes what appears to be a brass pressure release button so I expect that's what they intend.Overall, I recommend this product because it fills presta valve tires from a compressor at a very friendly price with a little practice.Tom H

Its kind of hard to use it plus the meter its not 100 % accurate. unless i got a defective one. if i did i would like a replacement :)but overall its an ok product.

It's super accurate, very well built and tons of accessories! I should have bought this year's ago! I use it for my bikes including presta (with included attachment) on road and mountain bikes. I used a digital gauge check the accuracy and it was only at most plus .5 psi where the needle showed. Given it shows 2psi lines that's great! I like my mountain bike at 21psi and I can accurately get it there with this! Highly recommended!

Should have tried this right away. Didn't try to use it for about 4 months and when I did the gauge was not even close. Too late to return it so am going to buy another gage at home depot tomorrow. Evidently gage is junk.

Works about 40% of intended use. All works ok, the guage, the trigger but the end does not ever hold onto the valve stem. Meant to be a one-handed use tool but you have to hold the end on to the valve stem or it will leak. I think its made too cheap. I bought another one prior to this one but the end on it was so cheap that it only lasted a few uses before I had to hold it against the stem to inflate a tire.. I think they could have made a better product thus the low rating because of the valve stem holder end....not holding on to the valve stem.

Not exactly pro-grade but for occasional use hard to beat at $10. Gauge seems accurate. Throwing in a bunch of Presta and Schrader dust caps and other stuff was a nice touch. The instructions have a big warning saying "FOR AUTOMOTIVE USE ONLY" but also have picture of it being used on a bicycle. That was almost worth the $10 alone.

Great little gadget. I bought this to seat the bead on my tubeless bicycle tires, which needs a lot of air fast in order to work. This does the trick for that purpose, and I have the benefit of being able to fill up the tires on all my equipment (cars, snowblower, dolly, etc) a bit more easily as well.My only complaint is a small one, and it's the quick attach adapter...it doesn't create the best air tight seal, and requires a little bit of playing with it to get it to seat all the way. This isn't a problem for most applications, as 95% of the air makes it through, but when I needed to seat the beads on my bicycle tires, you need a perfect seal and that took a little time to get right.Overall, for the price, this thing is great.
