So one thing I tend to do when researching a product is search for “<model_name> specs” or “specifications”. I usually try to see if they have a marketing slick or one pager of what the item has to find it out. If worse comes to worse I’ll browse the user manual, if something is ambiguous but majority of the times that search will help me find what I need.
Why does he have to “urge” them. Isn’t he in charge of them?
