Review on Tachometer Walfront 2 5 99999RPM Non Contact Measurement by Victor Garro

Just received, works great. The reflective tape came off on the first try but it was my fault for not cleaning the area properly. I bought this to test the speed of a Makita router. I wasn't sure if it spins at 30000rpm as advertised on the router (runs so quietly). I have 29790 rpm on the reader. you count. It doesn't matter which 1% is different, I'm still satisfied
