Mr. Earl's technique, timing, and - particularly important for this topic - naturalness are very good. That's a lesson in itself. Out the roughly 70 minutes of instruction, over an hour is devoted to switches performed seated at a table. The ad claims that the switches require no lapping, and indeed decks are never dropped, or raked off of the table, to fall into your lap. However, in many of the switches the table edge is used to conceal decks both before and after the switch, so the feel and appearance of these switches is similar to lapping. A short segment at the end, under ten minutes, covers a few stand-up switches, which, notably, can be done without wearing a jacket.
No routines or applications are taught, so this video is recommended if you already have one or more uses in mind for deck switches and want to find the best possible methods. None of the switches require any exceptional dexterity or coordination. However, most of the switches are best suited to confident, relaxed performers who have spent enough time in front of audiences to make their sleights flow seamlessly with their natural movements. If you're not yet comfortable performing, say, card-under-glass or gambler's cops, you might find the methods feel bold beyond your comfort level, or difficult to do without telegraphing your punch. But if you're ready to be a serious student of deck switches, this is required viewing.
