Delivery was fast as I remember. It was purchased ahead of time so it arrived much earlier than needed. The oil works so well at low temperatures, seems safe. I am just concerned with evaporation rate of this costly oil when it works at higher temperatures (e.g. 60 deg C).
Pros: safe, low viscosity at low temperatures, transparency
Cons: none so far, guess the price has to be that high for this kind of oil
