When I ordered this I thought it was just a dumb 3 digit 7- segment display. Its actually what it says it is: A tiny little voltmeter, that kicks in at something over ~ 2.5 volts. It read my 18VDC battery as 19.3V - No Load - which is probably about right.

Could be added to my tennis ball machine for a visual output of the speed of the 12vdc ball feed wheel motors.

Very cool.

Perfect voltage readout for 12 volt battery systems. You need to mount this a case or onto a circuit board to be useful, but it is an excellent and inexpensive voltage readout device for any small project where you need to know the voltage greater than 2.5 volts.

nice little item. no frills, small in size, unobtrusive and exactly what i needed to finish my job.this will give the it a nicely finished appearance as well as provide the information needed at various points. enough cannot be said for these folks and their service. it took awhile to get these and even though the fault was not theirs they did everything possible to get replacements to me. in my life i have never experienced so much service over so small amounts of money. here you will truly find people who know that the future depends on what is done today.
