Solid gadget. When motor or wheel prepared properly and reflective tape added, measures consistent RPM number. Tested with three cordless drills, measured RPM was within less than 3% difference what manufacturers stated on the drill speeds. So far no complaints.

Прибор работает. Удобные режимы - считает обороты, импульсы в прямом и отраженном свете. Чувствительность неплохая - реагирует на взмахи руки. Пришёл недели за три, с треком. Немного помяли коробку. Прилагается белая липкая лента для меток и инструкция на китайском. Продавца

The tachometer shows most of the time the correct reading. They telling the measuring distance upto 2 feet, but actually it is less than 6 inches. And the battery indicator always shows minimum reading only. The user manual tells alkaline batteries included but the seller not giving the said item.

Pleased with the tachometer. It works well on several rotating objects. It measures the PTO speed on the tractor. Recommend this product.
