Review on 🔧 Boulder Tools Heavy Duty Rapid Tire Deflator Air Down Offroad Kit – Precision Release Button, Glow-in-Dark Feature – Bonus: Valve Caps, Valve Cores, Valve Repair Tool – Fast Deflation for 4x4 Off Road Tires by Sean Powers

Works well and deflates tires quickly. about two months. I used it once a week when I went off-road in my jeep. This doesn't work now; I am a very careful and prudent person and have always used it very carefully trying not to damage the deflator or my tires. An attempt to contact the seller was unsuccessful as support is "not an option" according to the message received. If you decide to buy this, keep in mind that it will soon stop working and may not work properly. Update 4/15/19: Okay so I'm increasing my rating from 1 star to 3 stars as I was contacted directly by Boulder Tools and they sent a replacement free of charge and no questions asked; It was pretty cool when they backed up their guarantee. I've only used a new deflator a few times at most; So far it's working well and only time will tell, I'll update the review again in a few months. So far, so good.
