It was convenient to measure the rotation speed easily. If the distance was too close, it was no good, about 20 centimeters away was good.

I do not like the price or accuracy. Though the thing which I used up to now is spiraling and the number of revolutions comes out, I purchased it because the installation was troublesome. I think that it is bought if it can be easily measured "about the accuracy". Since the included reflective seal is heavy, it fly away as soon as the rotation speed is fast. It is recommended to prepare thin and difficult to peel.

It is good that the cover is attached and the LCD screen is protected when not in use. It seems to be okay even if the worker handles somewhat roughly or a little water.
