This light has the stated performance. The brightness of the light can be adjusted as well as the sound. I only used one filter; he did what i expected. I haven't tried other filters yet. The height is adjustable and works well with my medium sized laptop. It's surprisingly light; Hope it's not fragile. I like that the battery is rechargeable; So you don't have to deal with the electrical wiring during use. Unfortunately, it didn't transform me into a glamorous beauty, but then again... he didn't promise.
