I am blind and thus tend to have a harder time managing the heat on my bowls alot - Been using this bowl for about a week now and I've never had an easier time smoking by myself - The tray is awesome to carry the coals to my hookah with and being able to rotate it is a huge blessing - I was shocked to see how small the opening was at the bottom of the bowl, but it endded up fitting on my hookah perfectly without the use of a gromet - The vortex design hits like a champ - One other huge plus for me is that I don't have to worry about breaking it due to not seeing it and accidently knocking it over - Now that I have this bowl I will never use another kind of bowl again - I really don't see how it would be possible to make a better bowl -
