Review on 📏 Accurate Speed Measurements with Extech 461920 Laser Tachometer Counter by Andrew Frison

This device works as advertised. I've used it on a number of projects and measured fan speeds in ovens. It fits my needs perfectly, but may not be strong enough for daily use in the field. The plastic case feels thin and is unlikely to survive drops from any height. It would be better if the case is made of a softer material that absorbs shock. Like I said, he's doing his job.
