Bests & Worsts Reviews from Amazon

I like the multimeter - it's not the most accurate thing in the world but it works great for the price point. What I can't stand is that included in the box was a signup to one of these 'We ship you free products for reviews' websites. These are basically buying 5-star ratings (because they cut you off if you don't leave positive reviews). It completely destroys the Amazon rating system, and I can't trust the reviews of any product that is sold by one of these companies. Leaving 1 star to counter the bogus 5 star reviews.
