I have one glass top humi and I keep my hyrgo on top of the cigars so it can be read through the glass, nice and convienient. I also have a solid top 300 countwith a remote temp humidity guage. The reciever is on my desk so I know that my huni is at a confy 69% humidity right now. I like the glass because like SFG said you can drool over your cigars and not have to open you humi to do so.
