Reviews of the aqara switches?

I know the search function exists, haha, but I’m really interested in hearing personally if their switches are worth investing in and replacing all my sockets in my apartment?

Should I go with the single switch, or a double rocker? Do they work well for dimming? Everything I read seems conflicting.

I understand perhaps the double rocker would be better for the dimming and other functions on single switches, and on the couple of double dimmers I have the aqara double rockers will work for those too.

Any obvious problems my electrician is bound to tell me if I bring him in to do the work?

I know I don’t need a neutral as my house in London was built about 5 million years ago. Or close.
