    1. Good Product

      It's my first time in R/C and this was easy to use with a great price! on 11th Mar 2017

    2. Does the job

      Very happy with this alarm! Super bright screen, loud and small. Two thumbs up! on 9th Mar 2017

    3. Good product - Lousy support

      These little gizmos work well but they come packaged with absolutely no instructions. I am surprised that FT would sell something with so little concern for the satisfaction of their customers.

      There's a little button under the buzzers that you press and hold. It will advance the alarm voltage value to your desired setting. Here's a link to the forum:

    4. Great little sucker

      This thing works well, and you can use it to check your batteries before you get to the field. This little guy is also very loud, and works well even at long distances. on 8th Jan 2017

    5. Does what you would expect it to do.

      First, I would like to warn you that this is incredibly loud. I would not recommend plugging it in for the first time while your wife is sleeping. It is very durable. I have crashed my multirotor many times, sending this flying through the field behind my house frequently. Overall, it is a great product, and it is well worth the investment to keep your hobby safe. on 14th Nov 2016

    6. Very Smart Thing To Buy

      This is a very good product and I am super glad that I purchased it. Very high quality and very affordable. The only downside is that It does not come with the kits. :-) on 5th Sep 2016

    7. No Install Instructions Included

      No instructions for use or installation were included in the package. The print on label attached to product is way too small to read, at lease with my old eyes. Suppose I could find a magnifying glass to read label. on 11th Aug 2016

    8. A "must have" item.

      This little device is awesome! It will save your batteries from over-discharge by sounding an alarm at your set voltage. It also gives you a visual display of your total voltage and cell voltages. The device isn't the most accurate, but gives a close approximation of battery status. Since you can only fly one plane at a time, you don't really need more then one. However, if you lose it or it is defective, you will be happy you ordered two. Plus they are cheap! on 17th Jul 2016

    9. Invaluable!

      Great for preventing over discharge. I make all of my students fly with one. on 21st Jun 2016

    10. What a device

      When hooked up correctly not only does it sound the alarm when the batteries are low, but before that it tells you what each cell voltage is at and the total voltage of all cells combined. Great to have for before your flight and after. What with they think of next!! Great device to have. on 6th Jun 2016
