I own a LF3XT, owned a LF5XT, and hope to soon own a Clicky (but not at the expense of my LF3XT :ironic
. The LF3XT amazes me on many levels. First, the build quality is the best I've seen under $100, and often over $100. Second, the beam is perfect, a very rare feat using a CREE XR-E LED. Third, the price is far below what I'd expect. And last, the UI, but that is subjective - you may like the LF3XT or Clicky UI better, and can probably decide based on reading.
I do however have a few problems with it. The whine is annoying, but not nearly as bad as my LF5XT was. Unlike the LF5XT, you cannot acess momentary high directly from off, but have to turn it on first (which now has no delay). And the switch has a fairly long travel, considering that you have to depress it all the way to activate it.
The reason I'm looking into the Clicky is the quality and possibly the UI. Compared to the LF3XT, I don't think it offers many other advantages, which is not very good considering the huge price difference. Then again, post
, quality always seems worth it
