This product can be used as a replacement for the Cyclone Bowl that comes with the Arizer V Tower and the Arizer Extreme Q. The Tuff Bowl functions the same and produces the same high quality vapor as the normal Cylcone Bowls, with one important difference. The Tuff Bowl is much harder to break. This is still an official Arizer part, but it is designed with an additional protective silicone-sleeve layer that makes the glass much more shatterproof. If you have had troubles with continuously breaking your glass components in the past, this upgrade is a great option.
