Review: Actually really good - Installation and setup was easy except for a problem updating the firmware which failed three times. Only a device restart resolved it - option in the app - but two power cycles before this didn’t help for some reason. Once that issue was resolved set-up was a breeze. Video quality is clear with high definition and notifications are near instantaneous. There is a slight lag in the video streaming by around 3 seconds but it’s no deal breaker, me and the missus tested it with a conversation through the door bell and her phone and it worked fine. The build quality of the door bell is high too. The doorbell is also linked to my Alexa Dots and Shows around the house acting as house wide doorbell chimes, in addition to the chime supplied with Eufy doorbell. There is a slight 2 second delay for bell chimes sounding on Alexa devices but again not so delayed to make it useless. The only downside is video streaming from the doorbell to an Echo Show - there is a good 30 second lag/delay between an action in front of the camera and seeing it on the Echo Show screen, And it buffers and disconnects a lot from the Echo Show when streaming video. So I won’t be using this for watching the video feed over Alexa unfortunately. All in all though it’s a cracking thing and works really well. The app is professional and full of features and configuration settings to allow you to choose motion detection zones, video quality for streaming and recording etc etc. Oh and it has 4GB of internal storage for video storage which is more than I expected. Very impressed and got it on desertcart Prime day with £50 off. Update 20/11/20 The Eufy doorbell is still performing well after a few weeks. I thought I’d update this review as the video feed to an Echo Show device seems much improved. The delay now, for me at least, is only 5 seconds. The feed does end after a few minutes but that appears to be by design.
Review: Nothing to fault, great buy! - This is a great bit of kit. It ticked all my boxes on requirements, and in fact more due to the compatibility with home Alexa setup. The doorbell is sturdy built and smart looking, very easy to setup, just take it one step at a time. I purchased a separate MicroSD card and mistakingly bought a 512gb card, it takes max 128gb MicroSSD so I had to get another, mentioned so no one else does it :-) The app on the phone is slightly sluggish to connect to the doorbell, even within range, but not an issue as it alerts fine and connects instantly when the bell is rung. I read battery is an issue, however, I charged mine to full when I unbowed it, and it's now been up 15 days and has only gone down to 74%, so unless you are sitting there watching the neighbours throughtl it constantly, battery life doesn't seem an issue at all. The additional plusses are no subscription and it's portable (I haven't hard wired it but everything to do so is supplied, with jumpers to use existing cabling) - as I plan to move soon.

### ⭐⭐⭐⭐ Decent for the price
*by C***L on 27 April 2026*

Decent enough for the price. Fairly easy to use and the camera quality itself is quite good. Had trouble connecting it to the mains which I was not able to do in the end. The App is decent also but sometimes does not record things. Size looks a bit bulky but I guess that is because of the battery. Battery life is decent, but is annoying having to keep an eye on it and charging it
