I bought a similar block off ebay a few years ago and it had a habit of getting stuck in my tools. So I rarely used it. These two did a lot better. They've breathed new life into my 18v Dewalt tools with 20v lithium batteries. I've read some reviews saying that storing the battery with these devices causes it to slowly discharge, but I usually separate my batteries from my tools if I leave them overnight I haven't noticed.
