Adjustable & Automatic
Lock-in your psi once and deflate your tires again and again. The deflators automatically stop at your desired psi without your help.
Screw On & Walk Away
Once calibrated, just screw on to the tire valve and grab a drink while they do all the work. Simple to follow instructions ensure smooth setup and operation.
Save Your Back & Knees
Stop bending over or kneeling for extended periods trying to deflate one tire at a time. Air down all 4 tires at once while you just stand there and smile.

This works great, super convinient. But one of the valves on my copy is a defective with uneven threads. Be sure to check them before heading out on a trip.

Easy to use - and that pressure gauge is fantastic. Solid brass construction for the deflaters. This comes with detailed, clear instructions, in clear and colloquial English (refreshing), down to being upfront how the plastic box could be better, and giving you a trick to close it. Precise deflation, I got everything within 0.5 psi no problem. Recommended!

Work as described and a great price.Easy to set up. I set them up on an extra tire in my shop and checked each twice. Accurate within 2 lbs.I have always used the type that removes the core and slides to deflate and have 3 brands of them. Old knees don’t like squatting to do this as much as they used to so wanted to try this type without dropping $100 for the big brand.Used them at a trail ride last week and then checked pressure and all 4 within 2 lbs of each other. Very impressive for the price point.The gauge that comes with them is a couple pounds off compared to my calibrated gauge but so is almost every gauge I have including some decent digital ones so not a big deal. I didn’t buy for the gauge anyway.

Not a dial and forget type. Bit of a faff to set up but ok when done. If different pressures are required for different terrain I.e. hard to soft or powdery sand or rock/mud you will need to set up different deflators for the different pressures then mark each individual deflator with the psi. No bar scale. Also the “hard case” is a pain because it is not stiff enough to work with the clips on the case. Spent a good 10 minutes trying to get them to catch and have only managed to lock 3 of the catches out of 4. 4th one is impossible to lock because the case bends so much.

Nach kleinen Anlaufschwierigkeiten machen die Ventile was sie sollen.In einem verhinderte ein Span in der Dichtung die Funktion. Der war schnell zu entfernen. Super Verpackung. Schön wäre zur Psi Anzeige im Prüfer noch bar oder kpa aber so geht's auch.

Boulder Pro Tire Deflator Kit - Comes in a convenient plastic box with a snap lid, extra valve stems and caps included - just as pictured. Instructions are good, and the deflators are simple to set up. The quality appears as good and some name brands with much higher prices. When adjusting for the desired pressure the first time, I got more accurate, repeatable results by closing the cap (turning clockwise) about 1/8 - 1/4 turn when I first heard air bleeding out. The air bleed out will become slower as the pressure approaches your desired set point. I had to cup my hand around the deflator to hear when the air had stopped bleeding out. The gauge is pretty good, but sometimes gave inconsistent readings - usually within +/- 1 lb of the reading I got on the better quality gauge I keep in my tool kit. But, overall, I'm happy with the quality, the results, the packaging, and the value for dollar.

Got these to help me deflate the tires more efficiently. Tested them out once at home (will use them in the summer), they seem to work fine. Can't compare as this is the only brand I've tried, but they seem very solid. They are significantly less cost than the Staun. I didn't want to invest so much in the Staun in case I lose them, that would be very upsetting. Also, was not sure if I would like them, so when i saw these, I went for it.I did have one issue which I will explain at the end. These are very simple to set. They do slow down when the pressure gets lower, but that seems logical to me. I just come back and let the last bit out myself to hurry it up. I prefer to double check the pressure anyway. I got these so I don't have to crouch by the tires for so long anymore because it's getting a bit hard on my knees. Also, if it's raining, it's nice to wait under the cover of the back hatch instead of getting so wet next to the tires (especially horrible when others drive by).I really like the small soft pouch, very pocketable. I compared the gauge with several stick ones, and it seems accurate. I do like like this gauge much better than the stick ones. However, too bad the gauge doesn't have a nub to help manual deflation like the stick ones have.I gave 5 stars especially for the service. They included a simple but informative instruction sheet. They also follow up with emails to make sure you are satisfied. The issue I had was that one of the deflators was not working. It turned out that it was a manufacturing defect, no holes in it. I took a picture of it to help explain, emailed it, and the response was prompt. They immediately sent out a replacement and threw in an extra deflator. In my opinion, it was just a fluke with the defect, it happens even with expensive stuff. The service was top notch though, definitely not a fluke. Thank you very much, very satisfied!
