Review title: Not very good quality
Product review: I bought these as Amazon indicates they will work in the Nano and Hex bug toys. The price seemed too good to be true, when compared to what you pay for the Nano bug batteries in toy stores. I used them for the first time tonight and I was not happy. My son had five Nanos that needed a new battery and I ended up going through ten of these batteries in 20 minutues. Two of the batteries did not work at all. The other eight worked but the Nanos did not seem as "active" as usual. Several needed another replacement battery within 10 minutes. I still have forty batteries left so we'll see what happens with them.
