I've had the Arlo Pro 2 for the last 12 months and its been great. Installed them myself and everything is controlled by the app. I recommend getting the Arlo solar panels as well though, so you don't have to worry about charging the batteries. I just leave the cameras on 24/7 now that I have the solar panels.
lol that was much better than I expected!
Essentially. Its like an electric blanket for your feet. If you google Medisina foot warmer, its the first result.
