When I first told my husband I was going to order this 20V RECHARGEABLE BATTERY POWERED 150P TIRE INFLATOR AIR COMPRESSOR he seemed to not understand the value of it, or why I thought we needed it. In his eyes it was redundant, because we already have an air compressor in the garage that he uses to inflate the tires whenever they need it. (Or whenever HE THINKS they need it.)The fact is, I don’t know anything about using his huge air compressor. Nor do I know anything about the various attachments that make the various tools work. I also like to drive with my tires more inflated than he likes his tires. Every time I asked him to put air in my tires, it just seemed like he never got around to it, or he didn’t think they were low on air. I usually defer to him on mechanical things, because he is, in fact, a mechanic. I ordered this because I’m sick of nagging and I wanted to either be able to do it myself, or make it super easy for him to do. No more nagging. No more low tires. It hasn’t quite worked out that way.This thing works very well. It makes inflating tires no hassle at all. My husband has pretty much taken it over. He works on lots of different equipment at work and he’s always fixing the other employees cars at work. Everything has tires, and he’s been using it constantly. He says it’s great, and super handy to use, and great to have in the car.The problem is, whenever we need it at home it’s never in the car, it is usually at work. Now instead of nagging him to put air in the tire, I’m nagging him to remember to bring home the tire inflator, so we can use it here.Obviously this works well, and every house needs at least one! And apparently it’s a lot easier and much more convenient, than starting up the giant air compressor, in the garage. It’s extremely portable, which, in my case, may not be a blessing.Don’t hesitate to buy this particular model of tire inflator. My husband certainly loves it!
