Great value for the money. It's not perfect, but considering the price point, excellent product. 4 stars, mainly because of the touch buttons, read why below. Pros : Works well, both as a desktop lamp, and a magnifier lamp. The brightness is adjustable, brightness levels are well balanced Color temperature selection is a nice option. It looks good, and it has the perfect size for me. The magnifier works well. What could be better : The main issue I have, is that It is somewhat hard to turn on the lamp when it is dark, because the buttons are \"touch\" buttons, not physical buttons. So if there's no lighting at all, they are *hard to find*. You kind of learn where they are, and get by, but not very practical. It's a USB 2 style plug. You need a USB adapter to plug it in a wall outlet, not included. Don't expect the desktop base to hold the lamp in every positions, but it is heavy enough for most positions. Just as described, it weight 3.1 pound, manage your expectations. If you need to stretch it all the way, use the clamp that is provided.
