Well, we are TP-Link, so I can't really speak on Blink Doorbells were rated like that, but I can tell you about our products. We offer multiple types of doorbells, ranging from those that use existing wiring to power them to battery-operated and dual-power models that can be installed using either of the two.  Key factors on our doorbells are:

• Easy to install, with a complete installation generally taking about 20 minutes 
• Subscription-free.  TP-Link's Tapo doorbells can record locally to a formatted and installed microSD card, allowing you to use and record detections from the doorbell without the need for a subscription.  You do have the option to subscribe to TapoCare for cloud-based storage of clips and detections.  Details on TapoCare can be found here: 
• Doorbells can be linked to Alexa and Google Home, but like all of our other camera devices, the live stream is visible.  For security purposes, Voice Assistants will not work with Tapo Camera products. 
• Tapo Doorbells make use of your phone or tablet's push notification function so you can receive notices fast and securely. 

My recommendation is the Tapo TD25 or Tapo D225.
