I have blink, bought it through kohls when they had one of their kohls sales (since they partner with amazon). Was about 1/3 the cost of arlo. I like it, my only gripe is the app is a little slow when doing actions like going to live view, arming and disarming, etc. It takes about 3-5 seconds. I tested two way voice from work in aurora and could have a convo with my wife in broomfield.
