The
Light Shield Advance is a sturdy little piece of plastic. Not that it will be about to withstand a blow from a hammer or anything, but it's sturdy enough that it you won't have to be super careful handling it. The hinges that hold the shield to the back base are very tight so you won't have to worry about it swinging open. The connection is also a good tight fit so it won't fall out on you either.
On the back of the base, there is a dial which allows you to adjust the light level of the lamp, so while finding the exact adjustment can take a little time, it is really easy to do. Also, for anyone wondering about how much this light drains from your batteries, it's minor.
