Pros: Very, very bright

Cons: None

Overall Review: Well thought-out design.

Pros: Very nice and well thought out backpack; comfortable to carry loaded.

Cons: Polyurethane Coating adds waterproofness, BUT does not breathe against your back in warm weather. This is a dealbreaker for me; should have been mentioned in description. Mesh backing would solve the problem. Zipper system is clumsy, difficult to operate.

Overall Review: A good pack, but very questionable for use in warm weather due to the polyurethane coating inside. Looking into a return for refund.

Pros: Seems to work as described.

Cons: The smell of this thing is overpowering; apparently something leftover from manufacturing. I will actually use the thing if the smell ever dissipates.

Overall Review: Looks to be a good product, but the odor prevents use.

Pros: NONE

Cons: WENT IMMEDIATELY TO TRASH

Overall Review: DON'T WASTE YOUR MONEY ON THIS ONE!

Pros: I now have 4 of these and they all seem to work well.

Cons: Battery life may be limited.

Pros: Good enough case for the price.

Cons: Cover does not function as claimed. It will not hold the iPad in place in the lower slot. The sleep function causes my iPad to turn on and off repeatedly, forcing me to power off the iPad and then wait for it to power back on with the next use; opposite function of sleep.

Overall Review: Probably would not buy if I had it to do again.

This is an excellent caliper for the price. The original caliper had a slight defect and was quickly replaced. A good deal from a good seller.
