Hard to say because it also depends on the distance between the intended location of the Ring and your Wifi router. Maybe you can use another device to test the signal strength first.
No, it doesn't use SD cards.
It is very easy to install. I got it drilled to the wall outside my apartment, next to the gate.
It works very well but I would also like to highlight 2 things
1) You will likely want to subscribe the Basic plan to have access to all the features.

If you don't want any subscriptions, the Eufy may be a good alternative.
2) The battery takes a while to charge. You may want to purchase an additional battery so that you can just swap one out for charging. If not, your doorbell will be battery-less while you charge it.
I'm thinking of getting this device.
- since the device is located outside, will there be any issue with wifi connectivity?
- is there a sd card for recording triggered motion detector?
- is it difficult to install?
- is this a good and worthy device for its price?
