It is in your best interest to acquire. After much consideration, this tool emerged as the clear winner in terms of the price to quality ratio. Got pros: Pretty accurate, and it comes with two batteries. Plastic case. Full metal body. Con: Didn't operate very well till I figured out where to look for it. The only problem was that the sticker was adhered to the casing in a misaligned manner.
