    Best of the Best & Definitely a bang for the buck!
    I purchased the Sonoff 4CH Rev2 & Sonoff PowRev2 from gearbest and installing these switches wasn't a hassle at all and I'm loving it since its installation. It's easy to use and I have already paired it with my Google home as you can see in the YouTube video whose link, I have attached! I would definitely recommend these sonoff devices!

    Excellent product from Sonoff, it has 4 channels that you can separately control via WiFi or from the buttons on it. It has also timing and scheduling functions, wich are very useful. It cand also be mounted on a DIN rail. Very useful in home and industrial automation systems.

    Awesome product
    Easy to use, easy to install, works amazingly with the app and the IFTTT.
    I'm using it daily, wish there was a product for more than 4 channels.
    The schedule works perfectly and simultaneously for multiple channels.
    Easy to share with others just by sending them sms and connect them immediately and remotely, would have been better if you could set more than one admin (for sharing purposes).
    having more channels.

    Top Produkt perfekt verarbeitet
    Der 4 Kanal Sonoff Switch ist perfekt um mehrer Steckdosen oder Lampen zuschalten. in meinem Fall habe ich es für eine Aquariumsteuerung benutz um damit verschiedene Geräte anzusteuern.

    Die Verarbeitung ist wie immer auf höchstem Niveau und es gibt da nichts zu bemängeln.
    Auch das Flashen mit Tasmota lief problemlos.

    Wie gesagt ich kann diesen 4 Kanal Switch nur weiter empfehlen.
    Dank auch wie immer an Gearbest für schnelle Lieferung.
