as 4 months before you need to charge it up again. The
other good thing about this is that you won't lose power
and each time you use the reel the tension will be the same.
In the original, with a regular battery the reel would lose
some juice as the battery got weaker.
For me, the greatest advancement is the fact that it is
always on so there is not need to turn the gimmick on or
off. You pull out the thread and it working straight away,
