Hello all,
I wrote for my blog a short review on the differences and pros of the P9 Model in comparison with the M1. Also I summarized the tips in regard of the “right” 9V Li-accumulator in the article, which are distributed in this forum. Various pictures, e.g. in comparison with the M1, may be helpful for those that are indecisive.

Best,
