We have the lamp with us for quite a while in use. They must be used only as a decorative lighting in relative darkness. But it makes your job very well. Even switching the functions by turning on / off within one second works as described. The color change we find very pleasant: it is very slow and quiet - hardly noticeable. The price / performance ratio, I find a whole but not great. As we we only need such a lamp, the 5 (8 with shipping) invested but times.
