Will I get my money back
I had loads of batteries of varying sizes and was convinced that they still had power left in them and needed a way to be sure rather than just chucking them away. I opted for this battery tester because it can test most battery sizes. When it arrived I was pleased to see that it was fairly sturdy and after looking it over I tried all of the old batteries and found that most had power still in them. Only a couple need binning. I had also mixed up some new batteries which after testing confirmed that they were still full. so saved throwing our perfectly good batteries. The only concern that I found was that some of the batteries showed more than half life but in reality performed poorly when reused. I was pleased to say that I did save about 10 2025/2032 coin batteries which I had no idea if they were still ok or not. In conclusion you could continue to just test in other items but I found this tested was good to test loads of batteries I had stored like many people do. Will I get the money paid for this back-probably not.

To hot to handle
I'm unable to give 5 stars as I've only used it once, it worked well. However, using the battery that came with it caused concern. I fitted the said battery and the machine didn't respond. On removing the battery, it was extremely hot and the heat caused me to drop it to the floor. It took sometime to cool before I discarded it. The device worked satisfactorily when a new battery from my supply was inserted and did not overheat. People beware of the battery that comes with this device. I'm not sure what would have happened should I have not removed it. This could be a one off, however, be mindful.
