I've been using YI for almost a decade
I've been using YI for almost a decade. Initially they were great inexpensive cameras. In the past few years the ads have gotten out of control. Today I'm getting rid of all 8 I have because they're basically useless. I put SD card in them since I choose not to pay for their cloud, fine, whatever, I like having more memory anyhow NOW you get 90 seconds to view any camera then you are stopped!? Literally useless unless you pay for their cloud and subscription.
