I'm giving this three stars only because I can not find another unit that holds multiple AC lights in a single unit otherwise this is a two star item; the design Fails and it's cheap production quality. The designing engineer should be shot! it was designed to be adjusted by a three handed person - if I loosen the knobs the two bulbs go crashing forward in order to tilt the bulbs and then tighten a person needs to have a hand on each knob and a hand lifting the bulbs to the correct angle - very awkwardly designed. I don't expect this to withstand any longevity its very cheaply constructed and its a matter of months before it breaks if not weeks. If anyone finds a better mount that holds multiple lights let me know. three stars because it's a unique product
p.s. There is NO way anyone can give this item five stars and I am really offended by the reviewers that so easily give out five stars. Just because something works for you does not mean you should give it five stars - I occasionally eat at McDonalds and while it fills the appetite I think we can all agree it's not a five star restaurant.
