Con is that when they're connected to an HA system, there's a delay between pressing the button and the light changing.
The Pico and Connected Bulb remotes work slick, and can work with other z-wave devices. I use a Connected Bulb remote to control two GE lamp modules (one inside, one outside), and put the remote on the wall in a faceplate, so it looks like a hard-wired switch. Because the lights I have plugged into the modules are not actually dimmable, I use one remote to control two sets of lights (there's 4 buttons on the remote; usually one is off, one is on, one is dim, one is brighten).
If you're interested, I can get more details.
