Promising review: "Received this as a Christmas gift, and OH MY DARK LORD, I'M HOOKED! After a trial-and-error period, and a well-spoken Alohomora spell, (and handing it over to my 20-year-old son), we figured out how to program the commands. Surprise! No one had Confunded us — it was a matter of reading ALL the directions versus trying to 'Ron Weasley' the situation with random whacking motions towards the TV. (Seriously — I heard Hermione's voice: 'Stop! Stop! Stop! You're going to take someone's eye out! Besides, you're saying it wrong. It's LeviOsa, not LevioSA.') Now, with a Flourish (and Blotts) that would make Ollivander proud, voilà — my TV comes on, and with a Flitwick-approved 'Swish and Flick,' I've changed the channel. But wait, that's not all — with the twist of the Obliviate spell — volume up or down. Accio Happiness & Avada Kedavra old remote! I'm so happy I could... I could.. I could kiss Trevor!!! Well, a chocolate frog at least." —teemarie
