Confused starting times. No response from Calumet when emailed to confirm times. Had to visit Edinburgh office to confirm. Some people arrived an hour early and had, therefore to leave an hour earlier. Poor lighting. Had to ask to have the room lights put on [consensus of the course attendees] as couldn't see my camera to make adjustments as requested by course tutor. Requested a hand out or copy of presentation as aid memoir. Not received as yet. At least those attendees who had memory sticks got the hand out. I did not pay for this course as it was a gift. I therefore don't know the cost to my benefactor. However, had I paid I would not be happy. I found the delivery disjointed, and because of the lighting issues I couldn't always take advantage of the presented information. I came away getting the impression this was an opportunity to flog Calumet products with a " % off for today only" promotion. Based on my experience I shall not be recommending your products to others. Lost opportunity Calumet!
