I know this item (a software licence) can be tricky, because of the manufacturer not always being on the ball. So I chose Lambda Tek for ordering through, because have always had good experience with them in the past and felt confident that if there were any issues they would sort them. Sure enough, the manufacturer needed a prod to get it right, and sure enough when I contacted Lambda Tek about it they were right on it with their supplier to make sure that the order was fulfilled properly. Best service from real people. Very pleased.
