    Rated 5 out of 5★ by i love it its just what i needed for my rv. 07/04/2013
    Rated 5 out of 5★ by GREAT DEVICE OF CHECKING THE BATTERY 12/20/2012
    Rated 5 out of 5★ by Excellent Product Easy to use, accurate readings, nice easy to read bright display with large numerals. Head tilts for easy to read angle. 03/08/2013
    Rated 5 out of 5★ by Can't go wrong Handy, reliable, very large readout. The lights may or may not apply to your type of battery, but being able to rotate the face makes this very adaptable. 03/01/2014
    Rated 5 out of 5★ by Super Value and Accurate Bought for its two decimal readout and adjustable head. When I checked its accuracy against a $150 Fluke DIgital Multimeter, the Equus voltage was within 0.02 volts. Wow!Exceeded my expectations, and at $13 it is a great value. Every RV or Boat should have one as a primary or secondary battery monitor. 03/03/2014
    Rated 5 out of 5★ by Great product and value This product makes it very easy to evaluate alternator and battery issues instantly. Large digital readout. This is my second one. My first one lasted for many years. This is an excellent diagnostic tool and the price is hard to beat. 03/13/2014
    Rated 5 out of 5★ by Does what it claims to do. Allows me to check the battery voltage with and without a load and gives me an idea what the impact is of turning on accessories.Handy since it resides in the "cigar lighter" when taking measurements and doesn't require more hands than I have available.Use it to check battery condition before launching boat.Clearly not a laboratory quality instrument, but good value for price. 04/08/2014
    Rated 5 out of 5★ by Great real-time monitor for elec/charging system Plugs in and tells me precisely what the battery charge and alternator activity are. Acts like the old-time dash amp meter used to (don't know why the manufacturers eliminated that). Switch from car to car to check charging situation. It seems very accurate. 04/10/2014
