Worst range finder ever - Opti Logic 120XLA Laser Range Finder - Yellow

My girlfriend got me one for x mas. The next day I went to the archery range to try it out. I walked back to the 100 yard mark. It said 88 yards. All the readings I took were off. So I returned it to optics planet and their great customer service. I got sent another one. This one didn't even want to take a reading. So my take in all this: I got sent 2 bad range finders. I will never but opti-logic products again. What are the chances of getting 2 bad products in a row? Maybe they have a bad quality assurance rep.
Pros: has yards and meters
Cons: does not work/ not accurate
