Hrmm....Plan to get 1 normal dry box tomorrow ...>< Rm90 with selica gel ..
This one you have no control over the humidity, and the hygrometer is analog type, it's less accurate and requires calibration once in a while.
Here's something interesting to ponder, I have a digital hygrometer which is also not 100% similar reading with the AIPO drybox, but close enough, around+-5; I tried putting the hygrometer in my camera bag and in my cupboard, the humidity level is actually around 40~45, the digital hygrometer has record for max and min humidity.
Oh, if your room is air-conditioned, the humidity level in the room will drop when the air-cond is running.
What you need to worry more is the condensation, when you move from cold room to a warm room, the sudden change in temperature, if you operate the camera immediately, you will notice condensation at the front of your lens. So, for those staying in high rise building, you can experience this especially during a cold night and you try to take some landscape photo from your balcony, etc.
