The Groomer Essentials Cordless Clipper is lightweight and very well balanced. It has two cutting speeds (3,200 / 4,000 RPM) and is compatible with all A5 snap on blades. It comes with two li-ion batteries. Each batter has a run time of 127 minutes and take 130 minutes to charge. It can be used with the charging cable plugged in for additional run time. The Cordless Clipper also comes with #10 steel blade and 4 guide combs.
These are decent clippers. The blades included, I was told were Amazon knockoffs, and hither were misaligned. The sharpener wouldn't even adjust them for me. The run time is good, they do in fact, cut well, and have no problems running a wide blade. The end cap on the batteries pop off easy. Other than a couple of minor issues, they are clippers I reach for every day.
Do not buy these clippers if you are a professional groomer. They will make your day longer and more frustrating. They do not cut well and the battery life is very short. You have to go over the dog multiple times to get the right length. In the process of making a return actually. Stick with the name brand if you want good results.
