Product review (4 stars): Do Not Trust the hygrometer on the unit!!!
Do Not Trust the hygrometer on the unit to keep the proper humidity for your gear.

Seems to work well, however the hygrometer is pretty far off from correct. I have a separate humidity meter which I have calibrated and it reads roughly 20% RH off from the digital readout on the box. Thats pretty darn significant!

So, in reality that means the box is displaying roughly 17% RH off from the actual RH. And for the price of this dry box that isn't right. Thats pretty far out of spec.

I would love to hear back from the seller or find contact information to the manufacturer so I can fix the issue. This is not a cheap box.
