I do not know if Joseph is trying to be funny, or if he failed to pay attention to the tutorial dvd.
This item is fantastic! (Yes... imagine that in the 9th Doctors voice...)
I have been trying to get the hang of IT for the past year, and my previous ITR was very dodgy... I was scared to use it in fear of breaking it, because it DID take roughly 45 mins for me to repair the thread.
I have been playing with my Tarantula II since it arrived... really, really easy to get the hang of, if the thread does happen to break, it is, literally, just a couple of seconds to fix it.
I have, using this, lost my fear of the thread breaking... in fact, I even managed to repair the thread in front of someone after I broke the thread at the end of a levitation, just before I went to do another effect, without them even noticing.
(This was a home environment... not a working performance environment, however it was done so quickly, they did not even spot it)
My advice. Open the box, take your T2 out, to get a gander at your code, go watch the entire tutorial DVD BEFORE you play with it... because you will break it if you just jump right in.
