Product review (5 stars): So Far, So Great...
I ordered this roughly three months prior to the date of this review; I wanted to let the product "season" a bit before I wrote the review...  First, I live in Florida and although my camera equipment is kept indoors in an air conditioned environment, this is a rather humid part of the world and I thought "better safe than sorry."  Second, I drink the Leica Koolaid and have too many Leica lenses and bodies...so, given the significant monetary investment in Leica equipment, an electronic dry box made even more sense.

The review of the product is short and sweet...it has been fantastic!  In the sense that it has maintained a humidity level around 40%, which is where I've chosen to keep it...  I purchased a hygrometer from a cigar shop to keep inside the unit and test against its external digital reading; they stay within about two (2) percentage points of one another...  Further, this unit makes absolutely no noise whatsoever...none!  I couldn't be happier with the product in the first three months (knock on wood that it continues this way)...I will certainly update the review if anything changes...

Finally, I'll list what I'm currently storing in this unit, and I'm not embellishing (it holds a lot!)...  A Nikon D600 body, six (6) Nikkor lenses including the 70-200 and 14-24 (which are rather large), two Leica RF bodies and ten (10) Leica lenses (including the Nocti 0.95, which is sizable for a Leica lens)...  I also keep a few filters and two flash units in the box, one for the Leica and one for the Nikon (not sure they need to be in a humidity controlled environment but why not...it has the room!)

From my perspective, this item is worth the price if you have a meaningful investment in camera equipment and want to ensure it stays around acceptably humid levels...
