Beeps very loud (you can easily hear it flying 50m away), very easy to use and not expensive at all.
I only rate 4 stars because it is not accurate. The readings of cell 2 are always 0,2V lower than reality which is a big error. But it is always the same deveation so I set my alarm 0,2V higher than required. The other cells read out just fine.
I would buy it again

Got one of these for a tricopter build with 2200mAh 3S Lipo. The beeps are certainly loud, and will likely be quite loud enough during flight. I've yet to test it in anger, but it's unlikely to disappoint.
My unit is pretty much spot on with the voltage readings - within 0.01V of my decent multimeter for each cell, and within the display tolerance of 0.1V for the total.
The warning voltage was preset to 2.8V like previous reviewers have noted, and not to 3.3V which the instruction label states. I've set mine to 3.3V.

Bought one of these for use on my FPV tricopter. Gives a very loud alarm which can be heard from a decent distance. If you find the "beeps" a bit loud (for example if plugging in indoors/messing with voltage button settings) simply place a finger across the output "pipes" of the beepers and you'll get a very muted beep, easily quiet enough to not disturb the better half watching Emmerdale or whatever. 5 *****'s

inexpensive and reliable...... a must buy!
please check the alarm voltage though as the packaging state the preset value is 3.3v but both of my units were set to 2.8v.

I bought this inexpensive device following the recommendation of a 'pro' octocopter pilot who works for a film crew. I just have some 2 and 3 cell LiPo powered motor-gliders but love the ease of instant voltage checking of cells, as well as a settable alarm to remind me to plan my landing. I just think of this as a one off insurance payment for my LiPo batteries and r/c models...

I have a quadcopter with 4 Giant Cod 30a ESC's. They have limited input for programming but work well (very). The only problem is when the battery is getting low on voltage i.e. running out, 1 ESC starts to reduce its power to the control board/ motor first. This was causing the quad to tip toward the failing motor. At height, a complete flip over and crash. This little device has now prevented this happening, giving me time to bring the quad down under MY control. Plus saving the battery from over discharge, not an issue for me because I would have a crash before it got to that stage. Beep and alarm will get the laziest of people out of their beds in the morning !!.

I got four of these as I liked the ability to alter the voltage for the low volt alarm. I have checked them all and they all vary there reading wildly unlike the 6s version which is very stable but unfortunately doesn't have the ability to alter the voltage alarm. They are way too far out too even think of using.

A good device, no need to set time on transmitter when mounted on board.

Excellent device, tested with a pack under load and it started to scream when one of the cells hit just below 3.3V. Unloaded the cells measured approx 3.6V each. this might give me an extra second or two to land my quad safely if my timer is not enough!

Brilliant little device, especially at the price. I haven't been able to test above 6 cells but its accuracy seems good and the alarm is loud enough to make you jump. This is the first tester I've had that works OK on single cells and a JST connector will plug straight in and read fine; although the alarm is very weak on one cell.
When you first plug in a battery via its JST-XH type balance connector you get a loud beep and then the display cycles through total voltage then each cells voltage.
The small button between the buzzers steps the alarm through 2.70V to 3.80V and, the very useful, 'OFF' in 0.1 volt steps with each press. Testing it on a knackered battery I can confirm the alarm goes off as soon as any one cell goes 0.01V below the set alarm voltage, flashes a red LED at the same time and flashes that cells entry as well.
Being able to set all the way up to 3.8V means it can be used to safely discharge a battery down to storage voltage which is very handy.
Instructions are printed in full on the back of the device although a watchmaker's eyeglass is real handy to read them :-)
The only criticisms I can find is that each time the setting button is pressed you get a full volume beep from the buzzer (which is a bit much!) and the balance connector plugs in counter-intuitively i.e. upside down compared with other testers I've used neither is anywhere near enough not to give this a '5'.
