Overall, I love this machine. The image quality and portability are perfect for my purposes (Pregnancy and basic diagnostic scanning on sheep, goats, and pigs).
My only complaint is the battery charging routine- I wish there was an indicator for how much battery life is remaining (maybe there is and I just haven't found it). I wish I didn't need a coin to remove the battery. And I wish the charger wasn't 3 separate components. A car charger would be great too.
