No more of the time  consumming hole punching!
Here is a great idea :
Combination of great ceramic bowl, personal wind cover which really holds the heat in well spread even indoors, and a metal precut with holes screen.-
I had read on one forum that the spring action shown here is poorly done, but I have had 2 of these for awhile and they work fine . I like the time saved on punching holes, and can pick the screen up to check the tobacco for any reason if I want. The personal cover is much  better than the large conventially known aluminum  cover for holding in heat 
and keeping the slightest of wind out when smoking outdoors, but also indoors I use it to save on coal since it hold the  heat that mostly escapes.
Good deal.
