The first delivery attempt was canceled by Revain for an unknown reason. They called them and re-ordered all the items from the previous order. The new delivery was actually 4 days earlier than promised, I think the customer benefited for a long time. As for your microscope, I have it. The wired model is fantastic and we now have a wireless model which we are really looking forward to. After my soul mate was covered with 3rd degree flab burns, she removed the deep seated fat from my body. With a cordless microscope, she can now see much better while maintaining normal stress levels. Thank you for the quality we need so much. grams
