Good tool to have
Pros: I have not been using this device that long, but so far it has worked well for my purposes. I'm using it mainly to check the power level of battery operated sprayers that have no battery charge indicator on them. I think this tool will help me to preserve my batteries by not overly discharging them. I'm using a maintainer to keep the batteries charged after each use.
Cons: The display on the device is not lit making it hard to read in dim light. Other than that I love it. It does what I need it to do. I can hook it directly to my sprayer's charge outlet and tell where the battery level is at or I can hook it to a battery that is outside the sprayer with an attachment I have with one of my maintainers.
Battery powered devices like sprayers and such should come standard with a battery level meter. The vast majority of ones I've looked at with only one exception do not have it. This makes it VERY, VERY easy to ruin the battery on a sprayer either by over charging or letting it get undercharged. I learned this the hard and costly way.
