Informational as well as economical (both full length vids are packaged in one box), one thing can be gathered from watching these two Eurovids -- French people like group sex. Both vids show a predominance of group scenes, ranging from three to six performers.
Sex Fan Club is typical European (although, surprisingly, no anal other than one dildo insertion) fare, and although it's probably some sort of box office blockbuster in its native land, if you can't speak French it's plotless wall-to-wall sex. Most of its five scenes are group orgies, with the standout being a b/g bathtub tryst between a natural bodied brunette and an Ethan Hawke-type. Their cowgirl/doggie/mish is hot, and both performers are very visually appealing (And clean!).
Love Potion does have a plot in English, but it's not thrilling, centering around a witch who casts spells to make her clients enjoy group sex. It seems there can't be any sex scene without someone watching and/or joining in. Mish, cowgirl, reverse cowgirl, doggie, lesbian sex... but no anal.
Stock moderately if you've got a customer base who appreciates European sex.
