This doesn't look bad, but I prefer Wahl brand over ConAir. I cut my own hair, and I've had my Wahl for a long time. Requires occasional maintenance, but it always works great.
Also, these are NOT for your private parts. However, you probably can use these clippers with no attachment as a beard trimmer (I did for a long time). Bewarned that as a beard trimmer, if something happens to the blade, it can cut you if you're not careful.
