Libra integration with pocket ?

i see my new kobo has this feature

a quick google suggests its a bit like the send to Kindle system that I have used before, but I have to create a pocket account, add a browser extension...

I am asking here for feedback from others who use it with Kobo readers e.g. how useful is it, do you then leave the kobo wifi on so that it will always sync new stuff, what impact does that have on battery life...

I dont know for sure if all the Kobo range has this, or only some of teh newer models.
I tried searching for "pocket" in this forum but there was no obvious discussion thread - if I missed one, please point me at it
