Exceeded My Expectations - Highly Recommended
Okay, let me start by saying I'm not a scientist. I'm not into whether this tester is "under load" or "over load" or whatever those terms may mean. I know that amount of precision is important for some people. Understood.For me and what I do know is that this tester gave results that I expected. For batteries that I knew weren't working (because the flashlight or other item wasn't working), this tester indicated those batteries were DEAD. For new batteries that should be GOOD with a full charge, this tester showed GOOD/FULLY CHARGED every time. For some batteries that have been used in items for a while, the tester showed WEAK, or slightly less than full. To be expected. I tested batteries from Amazon and other retailers. Duracell, Energizer, etc. If the batteries were supposed to be new, this tester showed they were. If they were corroded, had been used for a long time, or were well past the use-by-date, the tester showed WEAK or DEAD.That's what I wanted. I did look at some of the testers that were in the under $10 range. I didn't like the way you had to hold button cell and CR2032 batteries to test them. They easily slid out of those testers if you didn't hold them just right. So, I spent around double the price for this tester using it to test literally every size of battery I had from 9V down to the smallest button coin batteries. I had over 20 LR44 and LR1154 batteries I use in my bike computers. This tester quickly showed me the weak batteries and the good batteries. I knew what they probably were based upon use and the date on the package. But this tester verified those readings.I also had some loose batteries that I literally did not know if they were good or bad. I put every one of those in the tester and wind up with many dead batteries, some okay ones, and many good ones. It was easy to toss out the ones that I couldn't trust in the future using this tester.I gave the tester 5 stars. If it lasts, it's worth 10 stars. Unless you need scientific precision using load/no load factors, this tester is awesome in my opinion. I will buy a second one to have when I invariably can't find this one. Highly recommended.

Great Tester
This is a really nice battery tester. I work building maintenance at a golf resort, so I regularly have to change out batteries in things like the key card door locks, TV remotes, and soap/paper towel dispensers. This tester is great at checking which batteries are good and bad. Nothing fancy, just pop the battery in and see where the percentage bar stops. Too easy

Battery Tester that Gives a Good Enough Idea of a Batter's Strength
This device is very easy to use -- you just have to learn the location for each type of battery. I know it's accurate for new batteries, but I have no way of confirming its accuracy for used batteries. I have some batteries that had already been rejected as weak but are showing as borderline good by this device. It's good enough to give an idea of the strength, but you have to get used to the degree of strength displayed by the device.

No more half dead batteries around the house
After years of using a hard to use and/or not accurate battery testers, I broke down and made this purchase. The tester arrived quick, the only "set up" is inserting a battery to power the readout and it was quickly ready to use. With options to check multiple size and style batteries, this may be one of the best tools in my home. It is very easy to use and to read the power level when displayed. Living in Florida, we keep a large stock of multiple size batteries for use during storms and hurricanes that may keep our power off for sometimes days. We were able to easily check our inventory, eliminating low power cells.
