These are really well made pieces with many different functions.
The 2 additional diffuser adaptors aren't any different than the stock diffuser except being more shallow. These currently overlap for me and I don't currently have a use for them, but who knows what might come out and they could be great for. They can give you the option of getting the heat closer to the bowl depending on configuration.
- The 30mm FMJ diffuser is heavy duty heat holder. The plus side is it offers incredible heat retention. This enables you, no it forces you to drop the temp to about 450 - 475. If you run this thing at 550: you will combust for sure. Really good low temp slow flavorful draws at 450. The thing to know about this is it is pretty heavy so depending on the size and orientation of your water piece, it could make it a little less stable unless you are using something like the Cube or Orb which I highly recommend for this adaptor Strong Center of gravity.
-The Stem Vape and combustion bowl adapter is nice too. It will definitely allow you to make use of your old flower bowls kicking around. To use it with my dynavap I drop the adaptor into a 25mm axial coil by itself with the narrow end up and crank the heat up to 600 -650 and just drop your dynavap in and wait for the click. I find this more useful than I had expected plus I get to use some of the nice custom bowls I have kicking around.
-The 18mm Injector is the one I use the most. This has many applications. The best is how well it works with my WOHW matrix micro dose bowl as a diffuser(pictured below) . It is a perfect diffuser with a tighter tolerance than the WOHW injector side and covers the bowl all the way down to the base giving great heat soaks. It also works in just about any application I also use my Old Head Terp Hammer and the bowls designed for it. Nice to have them both hot going back and forth.
-The 14mm injector adaptor will do anything the 18mm injector does but with a more narrow air pat.
I didn't buy mine from Vgoodiez but I wish I did. I highly recommend buying these from Vgoodiez if you want the best service. I bought mine elsewhere because Vgoodiez didn't stock them at the time. Vgoodiez is always my first go to.
