Should at least make it clear in your instructions
Oil is missing. It turns out that the lubricate oil  is not required and not contained in the kit. But in the instruction, it clearly says the oil is part of the kit. A little confusing for the customer. Anyway, wastes a whole week for delivery and returning,  and missed an important date (one full month) for the baby hair cut.  3 star, at most
