These are kinda nifty.
Got one of these in my Bolton case. -
Had it in there for 6+months and have only had to "dry" it once so far. Case seems pretty airtight.
Problem is, unless gear is in something that is airtight, the desiccant will always absorb moisture from the surrounding area.
I do see some gaskets in the pics. But how do they seal against the body and lenses is my question. If the caps seal onto the lenses, and body, using a gasket, this problem would be negated slightly. But just like opening a case, every time the cap is removed, moisture will be absorbed. It would also not be effective unless lenses and bodies were sealed well.
IMO, looks like a gimmick item. I'd rather go with a sealed case and our reusable desiccants knowing they work. And I have poor mans gear. No way I would trust these on thousands of dollars worth of gear.
