I travel quite frequently, and wanted a travel makeup mirror comparable to the one I have at home. The magnification of this one is good; and, unlike other reviewers, I haven't had trouble with the upper, 1X mirror staying on. The light works great if the batteries are brand new - however, that level of brightness lasts maybe two mornings. I am very careful to shut the mirror off when not in use; yet, I cannot get top quality batteries to light the thing for more than one business trip before I find myself gravitating toward a light in my room to actually see. It does have a port for an adapter. But, first, it doesn't come with an adapter; plus, I'm already packing charging cords for my phone and computer...it would just be one more thing to forget. Oh, and if I extend the neck, it tends to slide right back down. Apparently, it's a little too heavy for the design.
