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.
