Actually, there's nothing to dislike about Sinosend. I think that it should be a keep-it-forever kind of product on the list. AppSumo has many great programs, some good programs, and a couple of not-so-greats. This only falls in the great program because it's easy to use. The support system provided is superb, I find myself using it very often. If you can get it, I would. Not a long review, but that's my feeling.
