I must be missing something with this one, so please excuse my no doubt glaring ignorance, but this is called the hydro brick, but it seems you still need to buy or use your own Seperate water tool.
So how is this different to the other bricks that people already attach their hydrotubes and whatever else to? Is it just a female joint shape for easier attachment, or something else that i am failing to understand.
Thanks
The distinction is not purely ergonomic, or rather: in the case of sticky bricks vapes, ergonomics directly correlate to ease of use.
This style of vaporizer is best with visual vapor feedback because it is used with manual heating, and thus you can combust easily if you aren't paying attention--I can, at least, because I'm a little careless.
The design of the Hydrobrick makes it so that you can place a water tool right on/into the vaporizer's airpath, meaning that you'll be able to see the vapor rising and use that as a helpful judge when learning how to hit the sticky bricks type of vaporizer effectively.
Using a whip, for me, would result too often in combustion. Of course, not everyone likes hydratubes, and some will use a whip with the Hydrobrick.
But 18mm male is a fairly common attachment that many of us vapor-fiends wish were on all of our vaporizers, as it makes water cooling and different fun types of modding very quick and easy.
