Fills tires fast and digital display is accurate. u just set the tire pressure you wish for it to inflate to and hit start. It does the rest.
Easy to use reall light and fast working
Inflates very quickly, digitally set to the PSI of you choice!
Everyone should own this little compressor does what it says and if youveEveryone should own this little compressor does what it says and if youve ever had to fill up a low tire on a dark night in the rainYou push one button it fills up the tire fantastic
This device is very easy to use. Just follow the instructions and your tire will be aired up in no time!! I also like the lights( includes a regular flashlight and a red flashing light). I strongly recommend this device for women who are not mechanically inclined, like me.
It was a gift. The recipient loves it. It's digital, and automatically stops to your preset pressure. It has an onboard pressure gauge, so no separate tire gauge needed. The light is so convenient, for times when light is not available, not just for airing up a tire. Any time you need some extra light in or near your vehicle. Compact, easy to use, easy to store! What else could you ask for??
Works really well!have used it several times over the past year on my own, and my families vehicles.
I may have gotten a defective unit but when I tried to use this in my truck it blew the fuse. I've never had an air pump blow the fuse. I have returned for the slightly smaller slime digital inflator. For the brief period that it did work it inflated the tire very fast but didn't want to risk blowing anymore fuses.
I'm actually more impressed with the $20 version of this.. the $20 version is worth every penny. I can't say the same about this one. it really shouldn't cost over 30. but it does. Cons: The power cord is impossible to put back into the assembly. Get used to having the cords everywhere. So be sure to keep a box or something to store the unit in. The cigarette plug end feels incredibly cheap. if you pull the car adapter plug by the cord even once you WILL break it. The air and power cords come out of the bottom so the unit does not stay flat on the concrete when airing up the tire... Not very smart.. (unlike the cheaper version which I would argue is a superior product by the same company. Pros: airs up the tire faster than the $20 version, quieter, the unit is more rugged than it's predicessor. I got spoiled on the $20 predicessor. I thought this unit would be a littler higher quality considering it's twice the price. over all I would not recommend this as the cheaper version (also by slime) is better and half the price!
Would not put air in my truck tire. Do not waste your money.
