  A recently published article by Klapdor-Kleingrothaus et al. critiques the
limit on the stability of the electron obtained by the Borexino collaboration.
We respond here to the criticisms raised by Klapdor-Kleingrothaus and his
colleagues, and re-establish that our result is based on very conservative
premises and that the "indication of a signal of 1.4 $\sigma$" for the decay of
the electron in the $\gamma+\nu$ channel, reported by Klapdor-Kleingrothaus and
colleagues, is excluded by the Borexino result.
