Really poor. I have three of the go 4G cameras and as I write this, only one works. They drop out the cloud regularly and a camera that is unreliable is a waste of time and money. Flat battery or lost signal? You need to re-register which means playing with the qr code, which is temperamental to say the least. Someone from arlo will probably reply to this telling me to ask their tech help. But all their tech help does is ask you to follow the instructions. It's just a fault with arlo's cloud.
