Overall and outstanding update to the original SL20, that remains peerless. Having worked nights for 3 decades, a dependable durable light for all weather conditions. *Despite the claim the newer model is compatible with the orginal chargers, that doesn't apply for the NiMH model; tried it. Orginal charge time may be slightly over 24 hours.
Pros: very well made and finished, perfect upgrade from original
Cons: should have incorporated an anti roll feature.
