Not a good product
I looked at the Princeton EOS and was impressed by the throw. But Tikka's good reviews, it's long life, and the good price convinced me to buy the Tikka. What a waste. Bought two and both battery compartments pop open and lose the batteries. The on button also has broken. What's the point of long life if the batteries keep falling out, and it doesn't work. This happened to both in the first three weeks of use. Not to mention, the throw does not hold a candle to the EOS. Should have spent the extra money to get a really good product. Only plus is it's light and comfortable.
