Bests & Worsts Reviews from Amazon

I ordered this based on the many positive reviews and was disappointed to receive a unit that did not work. Pros: - Looks sharp Cons: - Difficult to turn on. It took 8-10 taps to get the unit to inconsistently turn on. - Inaccurate. The unit would give varying results, when it did work. Other times it would just flash an error. I even tried brand new batteries. - Most disturbing, some posts say people were rewarded with free items to give positive reviews. If I had seen this before ordering, I would have chosen something different. Other posts say they have now discontinued this practice.
