The set of glasses came with a defect in a large glass. But the Penguin team solved this problem and sent me another set. I was very pleased. Thank you very much. I put the highest mark and my recommendations.

I received the Multum in Parvo Deluxe. Nicely made, nice quality glasses. The trick works as it should. Quite convincing. Lots of fun. Perform on a towel-covered tray and don't worry about the mess. Currently, I use black coffee instead of milk. Works pretty good although there is some dilution. Going to try black food dye with water next. Absolutely glad I got this!

Like the Multum in Parvo Deluxe, this is a very well made prop. The effect and possibilities are different from the deluxe, but in my situation, I find that having both versions has its advantages. This version (Pro) allows you to pour small to large and large to small and anything in between. Deluxe olny allows small to large, but then allows you to fill the four smaller glasses with the contents of the large glass, which Pro can't do. Slightly different methods are the reason four this. Deluxe has 5 glasses, pro has four. If you do a lot of liquid tricks, getting both versions is not a bad idea.
