I like I can use a USB cord for power with this when the battery goes out. My battery didn't last long...maybe 5 uses of it then it notified me the battery was low. I did buy batteries from $1 store so not sure if that is why it drained the battery so quickly.Also, love the memory function. Slim and portable. I already have a bag that fits it nicely (glad that didn't add to the price of them adding a bag since I already had one). I am still waiting for my other order to arrive, however. It never did get a shipping number and says it is still processing.
