Simplisafe vs. Ring Home Security

I was in Costco yesterday and saw the Ring home security kit: https://www.costco.com/Ring-Alarm-Wireless-10-piece-Security-Kit.product.100424042.html.  Has anyone had any experience with this?  Not only is the price very competitive ($239 for the entire kit), but the monthly monitoring is only $10 (which includes video monitoring if you install their cameras or doorbells).
