Cheap tachometer

Has anyone had any luck using those cheap techometers they sell on e-bay for around $10. The type you wrap a few turns of wire around a spark plug lead.
I bought one to do some testing on my KE100, but the readings are all over the place.

Probably trying to read at real time, no delay built-in, if that makes sense. I have a "Tiny-Tach i've had for years but think they are about 70USD. They have circuitry that buffers that induction signal you're getting at the high tension wire. Stabilizing the display LCD.
