Pathetic product. Have tried each one - Hal***ix, W**ro, S***mo & S**ka. These companies are cheating their own countrymen by importing cheap chinese product and labelling them as theirs. Even the app used by each is a true copy of one another and can use any app with any bulb. Same problem exists with each. Whenever any color other than white is selected, bulb starts giving flashes every 1 minute. Same app and bulb vendor is dumping these products and these companies have purchased the dump from some vendor at throwaway prices and now busy minting money at the cost of crazy fellow countrymen. W**ro knows that the product is inferior so it has even blocked reviews for this products. Shame.
