Butane is non toxic !!, it evaporates completely !. you are not ingesting it, or breathing it when using oil. it's in your cooking spray ! used in the food industry for over 100 years ! it's not "stuck" in oil,wax,or budder after processing.
my soxy extractor has been on the shelf since the day I saw I could qwiso and get stellar results, comparitively. I'm not knocking the equip, great forever piece necessary for the alchemist, but not for the pot head. theres old coffee pot rice cooker methods too, but thats old school tar shit product. This extract is near pure active compound and wax free. there is no mold spores or sugars, or chlorophyls, or starch, or anything except what matches polarity with butane the fastest. it is the premium extract solvent for marijuana currently, not egotistically. c02 extraction yields less, but has the added benefit of costing 10k and not being flammable.
I do not wear gloves when extracting, or have fans running, or ever hear or smell butane. there is no exposure, and it allows proper recycling of the extract solvent. without fumes ever. I have run 14 runs with the same 400grams of butane with only a 70 gram loss of solvent. This goes along way in value added, if you've paid for vector you know. I think you should challenge the tamisium design patent, and sell it here cheaper first. his base model is a thousand dolars, cmon man, whats your labor rate ? machined stainless steel, several 30$ safety valves, a luxury custom fit padded case, perfect tested weldments, stainless braided hose, stupid simple, and will last forever. I got some lawn work over here if you're interested dude? working in industry briefly will show you what custom work, testing, certification,safety protocols, patent research, patent fee, printing and insurance really costs. this thing is worth twice what he charged me.
