I am delighted with my purchase. The hoop has three different lights, one cold, one warm and a third intermediate, in the photos you can not see the difference very well but in person it changes quite a lot. The size is great for close-up shots, it can even illuminate larger pictures. It works by connecting to a cable with usb connection so it can be used with any plug you have by mobile home or similar... Folds up or dismounts easily so you can store it and not occupy it.
