I actually used to own this very flashlight, lost it under a house about a year ago (I work for an exterminator), and was very sad to go back to my maglite. Paid $45 plus tax at the time.
Very solid feel to it, just the right size to fit in your hand nicely, little bit heavy to hold in your mouth. BRIGHT. BRIGHT. BRIGHT. Easily equivalent to a 3-D maglite in near field, not quite as much range though, and no way to focus the beam, though it does have a nice double-pattern.
The lens colors are just colored plastic in a rubber housing, just slips over the end and the rubber holds them on. Never had one fall off on me, only ever used the red one though.
I used mine daily for almost 6 mos. and the batteries still held about 45 minutes of charge when I lost it.
I’m in for two.
