I must agree, the pro is solid. Super easy to set up but my complaint is that the speaker needs to be a bit louder. It integrates really well into smartthings hub. Is it really a problem that it comes with 1 screw in mount? There's still the magnetic mounts you can use. The screw in one isn't more secure either. If the camera is mounted high enough and out of reach, I think that should be fine.
I'm going to buy a couple of first gen cameras to add to the system. It's a bit annoying about the battery situation (i love the Arlo pro rechargables), but I was able to find some cheap cameras to buy so might be worth the hassle of looking for rechargable batteries.
