Product review (3 stars): ok
luckily we don't use it very often, I got in more for the look. the lights are way too bright and just don't plan on using. it is very loud. doesn't come with an extender. we hooked it up to duct system, but the grooves at the top make it rattle and we have to adjust it sometimes when our air conditioning comes on. it was really cheap compared to others and serves its purpose, just not if we planned on using it all the time. If your doing brain surgery the lights will work well if they don't blind you.
