If your outlets are load bearing I think you have larger concerns.
Design might be a little cramped to have two USB (along with their transformer), two sockets, and Wi-Fi in a single box.
If you want that, a Lutron etup i the be$t option.
Also older houses with grounded metal boxes may likely cause wifi strength issues. Newer houses will have plastic so it’d be ok.
I find these to be pretty robust physically. I wonder if your existing outlets are worn out ?
My house isn’t older. Don’t have any problems with my existing sockets. The home just doesn’t have a whole house surge protector installed. I have surge protector sockets installed where needed though. Even with plastic boxes, things get a bit cramped in there.
