I'm very impressed with them. They are very well put together and plenty bright. They also came with a Delrin punch for installation as well as a free mil-spec 12 hour light stick and a coupon for 33% off any purchase of light sticks (which I plan to use). I don't know about you but I really dig freebees, no matter how small. Overall I'm very satisfied with the whole experience I've had with this company and would recommend them.
