After testing the SONOFF S40 Lite for two weeks, I'm genuinely impressed by how seamlessly it blends into my smart home setup. The moment I plugged in my bedside lamp and connected it via the eWeLink app (which took under 2 minutes!), I realized this little device was about to change my lazy Sunday mornings.

What surprised me most was the rock-solid 5GHz WiFi connection - no more 'device offline' errors like I'd get with other plugs. Voice control through Google Home feels magical when I'm cooking with messy hands and just shout 'Hey Google, turn on the blender'. The physical button also gives me peace of mind when internet goes down.

I did hit one snag - moving it between outlets caused temporary glitches until I power-cycled it. But the ability to share control with my roommate (who now turns off my forgotten coffee maker remotely) outweighs this minor quirk. After monitoring energy usage, I'm saving about 15% on vampire power for my entertainment system.

The build quality feels substantial, though I wish the package clearly stated it's a single unit. Pro tip: Create routines in the app to simulate sunrise lighting - waking up to gradually brightening lights beats any alarm clock. For under $20, this has become my most-used smart device after my phone.
