    Once you read the manual, it ends up being very easy to use. If you want better jaw to voice interaction, see this video. (The vidoe is not mine, just something I saw.

    I like the kit I bought, but it didn't come with the skull holes to mount everything pre drilled. So following along on the tutorial video is not incredibly possible for me. Took me longer than I care to admit that my skull want up to par, but if your paying over 100 dollars for a kit, its nice to have things ready to go. May alter review later, once everything is completly together.

    This product was the best!

    I bought a talking skull from monster guts, paid 500 buck and could not get the darn thing to work for the life of me. Then I saw this and bought it, I set it up in 30 minutes. Have to find the training video, so from the information perspective, they can definitely improve. However, once you find the video, it is a slam dunk. If you are looking for a talking skull I definitely recommend this.

    Head and shoulders above the rest!

    I have had time to mount this in the skull I have. The youtube of this being done was what I used. Not one problem! I have not had a chance to hook it up to run it but after all the studying I have done on talking skulls... PLEASE add a 6 servo board to your product line! If you buy any other hardware to make a talking skull you will find that your buying a car without the engine! What good is it? That and your going to have to download software and learn how to use it in order to make your expensive package work. Not so with the Scary Terry. They do suck at answering e-mails!
