K-2,is right obviously Makita,Milwauke,and Dewalt are the best out their and 18 volts are heavier duty.
Thats why depending on what you are doing,need to think of the weight too and such.
I am an owner of painting company I use my Ryboi all the time for past 4 years and live in MN where it gets -30 below and up too 100 degrees and that drill stays in the inclosed trailer all year long,it has been dropped,paint spilled on it,and other abuse.
It still works well grabs the bits all the times with no slipping.Has plenty of power for mixing paint in 5 gallon pails (spraying 60 gallons=12 pails handels it with ease.
Im not knocking what K-2 has said just stating what this drill has done for me.Gives you just an insight of how and what I use mine for.
