### ⭐⭐⭐ 3.0 out of 5 stars







  
  
    Fine as a tach, weak strobe
  

*by M***L on Reviewed in the United States on October 29, 2013*

This is a decent tach for the money, solidly built. The strobe on the one I ordered, however, was weak- not a very bright flash. If you need to illuminate something with it at a certain frequency, this may not be what you want. If you want a nice, affordable strobe tach with a wide range, you should be happy.
