Simple, efficient device
The Cannolator device is simple to use and efficient for a multitude of herbs. To further improve the customer experience, the instructions leaflet would be better in English (mine was in Dutch, might be a mistake). The "how to use" video on the site was an excellent replacement, having English subtitles. Further, the rest of the videos were in Dutch without English subtitles, which was a bit frustrating.
One could also make use of a description on what strength of ethanol should be used (and what is the effect if ethanol content less than 95% is used, e.g. 40% or 60%, which are typically found in alcohol shops). Also, what is the effect of double/triple extraction with the same ethanol solution? The instruction video also left some questions on decarboxylation (in case of cannabis) - should it be done before the extraction (resulting in some loss of terpenes), does it occur during evaporation (at around 100C), or should it be done after the extraction, separately?
