The install is pretty straight forward (unless the handy helper that lived at your house before you stripped all the wires back to the house for some reason?). Pop off the old doorbell, and bolt in the new connecting two wires. This unit came with an angle bracket (pictured) which I didn’t expect and is SUPER helpful for front door configurations like mine. The image quality is nice and I appreciate the notifications on my phone when someone is at the door since, let’s face it, everyone in the country pretty much has their phone glued to their hand. No more having to get off my rump to check the door like a caveman!Issues:1. During the initial set up, If you also have a router that runs multiple networks and automatically band steers, the doorbell will time out. This workaround worked for me: Turn off 'band steering', rename the 5g networks, save. Have your mobile device connect to the 2.4g network, set up the video doorbell, then change the names of the 5g networks back and turn band steering back on. Hope this helps keep someone from resetting their bell several times trying to connect.2. Two-way communication on my unit does not function. I’ve done the troubleshooting steps, checked the app to verify correct settings, verified the mic is open on my mobile device, but the communication continues to be one way. The doorbell mic/1-way coms work fine, but the two-way coms does not. Docking one star for this. If this gets resolved, I’ll update.3. I couldn’t find the dimensions of the device on the company materials, so please see my pic with a tape measure for reference. Looks like this device is slightly smaller than a RING Cam. It’s a little thicker than a ring, but it’s also narrower. Not good or bad, it just is.Overall, this is a nice little unit. I especially like the local storage option with a memory card. That’s a great value add for anyone that doesn’t want an additional monthly bill. 5 stars for cost, 5 stars for construction (looks very solid and the plastics feel durable), 4 stars for features, 5 stars for install. So what are you waiting for? You know you want one so you no longer have to get out of your chair to ignore the door anymore. =)
