Just at the fraction of the cost.
Works just like the ring doorbell.
Footage is clear and good enough for our needs.
Easy to setup with easy to understand english instructions, also there are a few video reviews on Youtube if you become stuck.
Easily paired with my mobile phone.
Hasn't skipped a beat since installing, gives you peace of mind who is at your front door or even lingering outside late at night with the built in motion detection which works perfectly.
Item is a bit on the large side so make sure you have a suitable location prior to purchasing to make sure it's going to be fine for you.
Not much else to say really apart from it works as it should, no issues and that I would highly recommend.
