Iing Arms green laser

Anybody have any input on this green laser?  It's sold mainly to airsoft enthusiasts, but they claim that it should hold well on weapon mounts and rifles.  The housing is solid aluminum and it comes with a pressure switch and a throw lever mount similar (identical?) to the A.R.M.S.  It is sold in Hong Kong in sites such as Redwolfairsoft.com.  Anybody have any input on these or any experiences or problems?  I'm thinking about buying one for my M4...
