a most have!
a most have! I always guessing what was the status of the batteries, but not anymore. I know know when to through the batteries out and replace them. Works very well! Not very expensive and can save you money and space (if you like me think the batteries might still work somewhere else).

great product
This is better than I thought it would be. It is extremely light and feels at first hand that it is poor quality as it has 'brittle' type plastic however I was wrong and it works well. It is quick and very easy to use and checks a large range of battery types and sizes. It shows the range of power left in the battery. I was going to throw out about 10 batteries that still had a lot of power in because others I had put in appliances with them had low power so you think they are all dead. It saves a lot of time putting batteries in things knowing they work. As it stands at the moment I would recommend it.
