The concept of these lights is great, but once receiving them I felt immediately disappointed. They're not as bright as you'd imagine from the pictures. The controls are cheap and it is neither a pleasure to use them or to physically hold and press on to them. To make it worse, there's one control for each lamp, but no clear instructions on how to use one control for both. Once I managed to sync the lamps to one control, the next day I had to start all over. the poor design of these controls makes the entire experience disagreeable. Have to return them and continue the search for the right setup.
