Build quality looks good and the instructions were easy to read English translations. But the module has two disadvantages. First, it is advertised as emitting 3000K warm light (color temperature). But the light it emits is much closer to the mid-range, say closer to 4000K. I'm not saying it's the light blue end of the spectrum, but I wouldn't call it "warm". The second problem is how the light is scattered. I installed it in a ceiling lamp so that the light is directed downwards. You can easily see the position of the LED emitters and the outline of the edge of the module. If this is used in an up-facing mount then it probably won't be a problem.
