This cordless drill has the features I would expect from a drill and worked well when I used it (along with the included drill and other accessories) to set up 3 floating shelves used. I used an air pump to inflate our basketball; it worked well. I like being able to select the air pressure units of my choice (pounds, psi, kPa or bar) as I can use the units printed on my tires without having to convert from one air pressure unit to another. Additional information about air pressure units: -- if I select kPa, it changes from 20 to 995 (in increments of 5) -- if I select PSI, it changes from 3.0 to 150 (I can press INCREASE or DECREASE -Hold button and it will increase or decrease fast, or I can press button and it will increase/decrease in 0.5 increment 5) -- If I choose kg/cm2, it will change from 0.20 to 10 .5 (in increments of 5) Note: It took me longer to inflate my tire with this air pump than with a gas station pump. When the battery is low I can use the included charging cable - by plugging one end of the cable into the air pump and the other end into the car socket. The battery has 3 indicator lights that give me an idea of how much life I have left before I need to charge it. I like this function very much. Bright LED on the drill. At night there was enough light to drive a screw in a piece of wood. The air pump has no light. What needs improvement: - After installing the battery on a drill or air pump, it's a little troublesome to remove the battery. - According to the product description page ". Devices equipped with a storage box are easy to carry during use, and convenient to store tools after use." The storage box is a carton of the product, and there is no handle To be able to take it with you, I store the box on the side of the box where it opens about the correct use of the drill and air pump as well as other illustrations Overall, I find the cordless drill, air pump and accessories useful for my purposes.
