It is one of the most satisfactory LED strips that one can buy for this money, as there are also "junk" products that are not worth even 5€. Since it is Wiz, it works perfectly with the app and cooperates exceptionally well with other Wiz bulbs and features such as Space Sense, etc., it never lags and generally works smoothly. I give it 4 stars though because the quality of its white and the intensity of the colors are not something wow. It performs exceptionally well in warm colors and is quite bright, but if you try to put a neutral daylight white like 4,000K, it won't do it as well and bright, but of course it is far better than many Chinese RGB ones. It tries to have white and color accuracy similar to that of the other Wiz products, which are excellent, but it falls a little short. There is a more expensive strip from the same company, which I assume will have more accurate color and more intensity, but I have not tried it.
