This is by far the best T&R out there that I've come across.
Pros:
Great restorations
Excellent teachings
Do not need a force
can be signed
immediate examination
setup is minimal! takes less than a minute
cons:
practice practice practice!
angles can be tricky, but not bad at all.
For the people I've shown this to, this has
gotta be the most convincing and most impressive T&R that I've learnt.
HIGHLY recommended!!
