Excellent Product... Essential Battery 'Tester'
This is an ESSENTIAL, Well Designed Product and everyone who uses batteries or has battery-operated products (all of us) needs one otherwise, you have no idea of the charge-status of your batteries... and don't just assume that batteries are always fresh with full-charge right out of the package or fresh when shipped/supplied with a battery-operated product. I have owned/used several battery-testing products and this one is by far the most versatile, convenient, quick and easy-to-use. Always TEST (even new) and DATE batteries (mo/'yr with a fine point 'sharpie' pen) at the time batteries are put into service in a device/product. Fortunately, manufacturers are trending towards more rechargeable batteries, but until then we all need our own battery 'tester' to know the charge-status of our batteries. This battery testing product is quick, easy-to-use and accurate... I use mine frequently and I would repurchase.

Solid product for the price
Works as expected. A tad difficult to pop out AA batteries--could be designed better for that. Love the numerous battery types supported and highly usable and intuitive design. Note that this is a relatively cheap product--it does not put a load across the battery to allow you to determine if the battery can really hold its displayed voltage under a typical load. You are basically getting a quality product relative to the cost.
