Very poor quality, and RPM's are way off.
This product is very poor quality. The battery compartment will not stay closed and the RPM's measurements are way off. It is unusable.

Good accuracy, but difficult to hold a steady reading
Good price, I like that a good amount of reflective tape was included. Accuracy verified with 2 methods; a calibrated signal generator (HP 3325B) and a tachometer calibrator (Sargent 1100A). The first method uses an LED from the output of the signal generator, set at specific frequencies, ex. 4.1667Hz should show 250rpm on the tach. I found this method to be slightly difficult, as the tach wouldn't always detect the LED (I used white and red LEDs). The second method uses a Sargent tachometer calibrator and a 20:1 ratio gear box (with a wheel that uses the reflective tape). That method worked better, as I was able to focus the tach's laser on the tape. I set the calibrator to 6000rpm and 20,000rpm. Both were dead on. So, the tach works well, you can trust the readout IF you can get it to display a constant, identical reading. I'd hold it on the target for 20-30 seconds and average the readings. 4 stars for the accuracy and price.

No good
This product did not work properly. The digital display was very erratic and measure into the 10s of thousands when it should have read into the hundreds.

Not so easy to use.
It is hard to get an accurate reading, some time it shows a much too fast of RPM. I have to get just the perfect angle on the reflective tape to get a good reading.
