As intensity is good, as light quality is quite ok.
As others say in the comments, it takes patience to pair. I managed only in "compatible pairing". Apart from that, there is a problem with updating the firmware. Mine has version 1.2.0 and the latest is 1.3.5 (at the moment) with many writing that if you have a version below a certain point, the update does not progress for some reason (stuck at 90%).
Of course, apart from these 2 issues, so far I have no problem with how it works with Google Home.

First smart bulb I buy, with the thought that the switch is far away and it is not a dimmer. From the bedroom it quickly moved to the living room. I had a little issue with pairing at first, but then everything was perfect. What I didn't know is that you can control it without being on the same WiFi (and therefore from anywhere you have internet) - something that you can definitely disable from your router settings. Not that a 7W LED (with brightness adjustment) burns anything special; the WiFi receiver may burn just as much. Last good thing, it keeps the settings if you turn off the switch.

It works as it should and looks very good for its price...
The company's application has some glitches, but they are quite rare!

Easy to connect and it happened immediately. Good lighting. Adjustable intensity and Kelvin if we want cool or warm lighting. I have had it for a week and it has not disconnected from the network. For those who experience disconnections, it is better to change the router to one that supports more connected devices. When I had the factory one, I also had several disconnections from various devices. As soon as I switched to a much better one that can handle up to 250 connected devices, I didn't have any disconnections from any device.

After a short time, it loses the connection to WiFi. If they fix it with an update, it would be a fantastic lamp. In all other aspects, it is flawless.

At first, I had some difficulties with the connection but it was fixed immediately once I installed the firmware updates.

They are not very bright, but they are really beautiful and adjust very well. I have set some to turn on low only at night automatically (house entrance) and others to turn on when I enter the house automatically, they all work flawlessly.

Also, something "silly" that I liked is that they are real glass and not plastic.

The product is good, but I encountered issues with pairing. I was only able to find a solution using compatibility mode, by instructing my Android phone to maintain the connection to the lamp's Wi-Fi even without internet access. Only then did ewelink successfully pair. So, I cannot blame the lamp for the difficulty, but rather how Android manages connections

This specific lamp fully satisfied me for the purpose I wanted it for. I needed a lamp that would resemble the appearance of an old Edison lamp, but with the advantages of a powerful LED lamp with smart control. Through the application, the lighting can be as dim and warm or as bright and strong as I want.

Value for money product.
In the positives:
1. Appearance
2. Cost - at 10 euros they are competitive with On/off, Kelvin/Lumens settings
3. Decent for the average user IF they have all the SONOFF bulbs. Otherwise, you will have 5 applications for your 5 different bulbs or you will work with Google Home/ ALEXA
In the negatives:
1. Latency in changes
2. Communicates with Chinese SONOFF servers
3. Requires work to integrate it into HOME Assistant
Don't forget, without smart switches, when someone turns off the switch, therefore the circuit, the bulbs are unavailable.
