The instruction manuel is very helpful if you never used one before. It includes the usual sorts of spelling and grammar mistakes, but at least you can understand most of it. They are very dependable and easy to use.

Inside the case, the foam insert snugly holds the light meter and even has a place for a spare battery. Comes in a foam-padded case that is made from high-quality plastic. It's not heavy or bulky.

Worn and tear is minimal after a weeks worth of usage, and it's held up to at least one fall. My wife is s packers fan, so it is an absolute blast wearing this hat any chance i get just to annoy her!

It runs off of a 9 volt battery which is included. The battery compartment is easy to open with just a little thumb pressure.

This light meter is accurate and simple to use. If you just want something inexpensive to compare light levels around the home or from one place to another, this is a perfectly reasonable, and reasonably priced, meter.

Reads all zeroes if you don't know the secret. Mastech, bother to mention the lens cap, and bother to include it in your illustration. It only accurately measures 4000k-ish light.
