I want to give this light 5 stars but I can't say it deserves it.  The head on mine never wants to swivel at all.  It feels like if I try and force it, its going to snap clean off so I've stopped trying.  Overall, the light provides pretty good illumination but the top will get warm fairly quickly.  Its been very tough and rugged as it has been dropped repeatedly.  So far nothing has broken or cracked.  The replaceable batteries make it convenient to use.  You can expect to get a good amount of time out of a single battery (depending on the life and condition of your batteries) before having to swap them out.  What would be nice is if they would develop an LED upgrade.  This would make the battery stretch for hours.
