I found the tool a nice add on for my sharpie tricks. It is easy to swap out while adding it to an
existing trick. I didnt like in the video they recommend just taking the cap off a Sharpie and
putting the Sharpie with no cap back in your pocket. Most people would react to "man you just got
Sharpie ink all over you".
My cap does not keep any charge at all. I have to charge it
right before I plan on using it. It seems very fragile with sticking in the charging cord and
removal. I would assume that most caps keep a charge longer than a hour, but I have had to adapt to
my current conditions.
Its worth adding as a add on trick but there a lot of things that
can go wrong (from getting it to stand up naturally, to inability for inspection, to reduced
battery, to durability) that it just be easier to ignore the trick rather than assume all of these
things that might go wrong.
