I bought this from Woot thinking it must be high quality since it retailed for $150. After I bought it, I noticed that the exact same item is sold on Amazon under different brand names for $20 up to $42. and at Walmart it only cost $18. Needless to say, claiming this is a $150 microscope is incredibly dishonest. In reality, it’s a low-quality, cheap USB-powered microscope. That said, it works fairly well and can take decent videos. Getting it in focus and keeping it in focus can be a challenge, but if you can manage that, it’s fun to play with. For $22, I am satisfied.
