I bought a glass top humi but after a couple weeks I ended up selling it to a friend and I went and bought a solid top humi. The reason for this is that sunlight ect can affect your cigars in a negative way. Also I found the solid top humi's have a little bit more cedar in them and may as a result hold more moisture then the others. Also, who knows how well the glass is sealed when the humi's are mass produced. Besides, it just looks shoddy unless you have only premium sticks on the top tray, and even then, as your humi fills up the top tray will look less and less organized Just my two cents
