Query: My Bemis lasted 15 years

This replaces my Bemis that I had for 15 years. Love the dual 2.75 gallon tanks. Uses same Water wick and air filter parts. I keep in Bedroom and keep fan on 1 of 9 settings, otherwise too loud.Refill tanks every 4 days. Digital read out of humidity much higher than the humidity gauge on other side of room, so I need to turn up the humidity setting to get it to work. Needs to be level for digital to work. Need to turn again after power outages. Not sure digital is an improvement over the old dials. Nice you can read digital from across room.
