It was not "ready to use" as stated because the battery was dead on arrival. I was disappointed that I had to spend $6.99 on site for a battery replacement for an $8.99 product advertised with a working battery. Total cost = $15.98. ๐ I could certainly return it, but like most people, the hassle of packing and sending it back is not worth the time spent on a product of this value.
