I'll just break it down into good and bad: Good 1) year warranty 2) Fast inflation compared to others I've had used (about 3x faster in my tests!) 3) Nice big display that's easy to read 4) Accurate pressure Poor 1) The unit is a bit bigger than others (important for mounting on a bike) 2) The hose is shorter than it should be 3 ) Forgets all settings when turned off, making all settings almost useless. For example, it doesn't remember that you set it to bike mode, or the last pressure you used in bike mode. That's all. It's fast and has a nice display, but it also forgets settings when it's off. It's a bit bigger than the others, but since it's 3x faster I think that's a bit understandable. If you need one of these for a car, this is the only unit you need to buy; the rest is too slow for that.
