this product is very easy to use & that's a definite plus in my book :D the only bad thing to this product is the clear plastic that comes with it that covers the light, but the plastic is removable after you unscrew two screws on the other side of the product, & you now have a usable light! :D i just set mine on top of my red eared slider turtles' tank & i'm done.
the light itself is a very good replacement for my old hood. the light has an acrylic (i guess?) lens that can be removed easily via two screws as to not hamper the rays. above the light in the base it actually has a tin material that reflects all the rays from up in the light back down which was a nice touch.
my gripe about this light is that i have it on an automatic timer and the light does not fire on 100% of the time... probly just a little defect in mine though.
