I actually preferred the multi-LED version better, but that's not saying much. (See post #50) One turn off for me, as someone who uses only NiMH, is the series/parallel nature of the battery configuration. Three cells in series, in parallel with two other three cells in series. You'd pretty much have to be anal retentive at keeping the batteries charged up so you don't run the risk of reverse-polarity charge when one or more cells dies. With this configuration, there isn't going to be any visible reduction of brightness when a cell dies until all six cells in any two legs are dead, at which point the other dead cells have already taken a severe beating of reverse charge.
