Trusted brand, successfully used in various rooms of the house

Always a good product, woeking great, connected several devices already with that brand

Excellent smart switch! Original Sonoff product. The build quality is very good. I bought it through a group purchase and got an amazing price, less than R$ 8 per unit. With the tax exemption for this amount, it was an excellent cost-benefit for those buying from China. I recommend the product and the seller! With the end of the tax on these small items, Brazilians will finally be able to buy gadgets from China at a fair price.

I haven't installed it yet because all the parts for replacing the old R2 units haven't arrived yet. This one was already top-notch, imagine these with this new technology.
