Hey, if you want to save yourself some influence as a Criminal, this is your best Fracter option. It's less efficient than Corroder or Paperclip but not by all that much, and those are the top of the line Fracters. Saker is decent, definitely usable. You probably won't ever use the derez ability though, unless you come across a Bulwark or Wotan or something.
In comparison to Corroder, Saker will cost you 2 credits more to install and to break ice will cost you 2 credits more against even-strength barriers and 1 credit more against odd-strength barriers. That's really not a huge efficiency loss if you value the influence more than saving 2 credits on the install and 1-2 credits to break Ice.
