There does seem to be extra risk when using a force deck, but there are a handful of very clever effects that are high impact, which is why I purchased this deck. The quality of the cards is poor though. These are not the professional finish cards with air flow finish. Still what you can do with this deck is well worth this price.

Great for forces but also really good for making gaffs with (especially T and R effects). You can also make you're own svengali decks using a one way force deck.

I would recommend getting at least one of these decks to put in your magic box because I find they always come in handy.
