In general recommend 2nd gen ring alarm in UK?

I know sometimes we get less, or eventually get, updates, features etc in UK, compared to the US. So in general do you recommend the Ring alarm in UK? I'm thinking of upgrading my alarm, from an old wired system, that rarely use, to a Ring alarm. I have a doorbell, and rear cam spotlight as well, so will have to upgrade to the £80/year for all these now to - worth it? I like the idea of the app integration, the ability to arm when forgot, notifications etc. Is it easy to setup? Is everything completely wireless apart from the base that needs a socket to be plugged in? How often do the batteries need changing on the devices? I've read a bit about the outside siren, seems some poor design choices imo. Why need 2 power sources for dusk to dawn? Why if wired permanently powered need 2 power sources? Obviously I want this high up, out of way for easy access, so how often do you need to change/charge batteries? I would probably go with the C cell, and ring battery, but no solar. thanks
