MPJA Response
Customer did return them, tested the four opened parts all tested good. Ether they did not know how a multi turn pot works or you need to adjust the pot clockwise to lower the set point. David

junk
Ordered ten of these, unpacked and wired up four of them with 16g wire and alligator clips. When I went to calibrate the alarm voltage they immediately alarmed and would not shut down until the voltage was above 13.9VDC no matter what I did with the adjustment screw. This makes them absolutely useless. I will be sending them back but do not like having to pay shipping to return DEFECTIVE merchandise. I did not try the other six as I decided to leave them in the original packaging. I was using a variable voltage DC source with a multi meter attached so I know that it was the units themselves that were bad.

Does exactly what it says...
All of the specifications match what is given. These things are loud, tiny and easy to setup. They are also very inexpensive for what you get.

Power hungry battery monitor
Idle current at 12V is: 10mA, Current when driving alarm is: 70mA

12V disconnect alarm
Using in camper to add 12v disconnect alert, primarily for LP detector. Used 4 16v/1500uF capacitors to power it. 12v in is thru a 0.2 amp light bulb, helps with charge spike but more to draw off residual system power before alarm, then thru diode so caps dont feed source. Takes it about half a second to trigger due to minimal self consumption of power, before it draws down the capacitors enough to trigger. Once triggered, capacitors drive alarm for about 1 1/2 seconds. Stoked. Size is really small. Had my doubts after opening the package, buzzer is only about 1/2in. But sound is piercing-no ignoring it or not hearing it. Amazed. Not this units purpose but it served mine perfectly
