This is 6 gallon (5 imperial gallons) fermenter unibody conical that hangs from a wall mount.

Ever seen it read about it?
I don't know what it's made from. Looks like plastic.
Does it allow thermal controls and probes?

I just asked the maker a bunch of questions
how the ensure the dry hop bag doesn't interfere with the out put?
Can a thermal probe be used with it & if so how?
Can it be used with a heat wrap?
Here is one guys impression:
He seems to love it.

Apparently it's a blow molded or rotationally molded plastic uni-body vessel.
I am guessing it is polyethylene. Most roto molded products are PE. It could be polypropelyene.
I know damn well it ain't PTFE
It's possible that it is Ultra High Molecular Weight Polyethylene (UHMWPE) that stuff can be roto-molded. But it's expensive.
If it's roto-molded it'll be fairly thick ( 1/4" maybe). As such you can drill it for thermal probes but Unless you can get a heat probe inside the thing I don't know about a brew heater. Prolly if you can get one on it it'll be OK. I mean after all how hot will you get it? 68 or 70 Degrees? All the thermo-forming plastics can handle that without any softening. Softening and molecular unzipping would be my concerns. Heat damages plastics. But the heat range of under 70 Deg F is not enough to worry about
Then there is the Plastic taste issue.
I can taste it when water is stored in most polymers. The one exception is the PET soda bottles.
Will it make your brew taste like plastic?
There is also the issue of vapor pressure. All materials (I mean all including Diamond, quartz, hardened steel, rye bread, and your neighbor's cat) all materials have a vapor pressure. This is the quantum of molecules or atoms of that material that desorb off from the surface and either escape or are adsorbed back onto the surface. Zink and cadmium have very high vapor pressures which is how they prevent rust. When the material is scratched the adsorption will rather quickly cover the exposed metal. Hell of a trick huh?
It's also why Cadmium is VERBOTTEN because the desorption trick contaminates everything. So they just don't use it any more.
Plastic has a vapor pressure. And before you start thinking I'm a whining Greener fronting for the ELF - - bear with me here - - human amniotic fluid (the unborn infant's swimming pool) and new born infant's blood have polystyrene in them (among other things) and it's simply because we have so much of the stuff in our lives that it is pretty much everywhere.
Whether that's a bad thing is another question. I'm just wondering about how much polymer I want to be consuming.
But at under $200.00 it is a tempting conical.
You can get two and plan on a third.
