Bought this item on Prime Day as a Christmas present for my brother-in-law. My brother-in-law is always working on something, owns three different houses and also builds kit cars, so I hope he finds this tool useful. Received it very quickly and found, as at least one other reviewer has pointed out, that the cut outs do not match all of the items in it (after removing one star). I turned on the caliper to check the battery and it cycled on and off as it should. To my untrained eye it seems to meet my expectations and is of good quality. However, I probably wouldn't pay the full MSRP for it.
