Re: Glass mod?
Ice chambers are great if they are large enough and built on a well made narghile other wise they are stupid. I love my KM and Furat ice chambers.
The mod is great because it gets better air flow and lets you use less shisha. I use it a lot although I use the super chief more often as it's less work to clean. If you have a funnel you need a mod. If you use the mod cover it it cooking oil before you use it. If it is still hard to clean afterwards get very small cup and fill it with hot water and powdered dish detergent and let the mod soak for a few hours.
