Great bargain price, first come, first served! Year-end clearance sale I have confirmed that the power turns on, but I have not checked any other functions. It's rechargeable, so no batteries are needed, and it comes with gel sheets, so you can use it immediately upon arrival. Due to the bargain price, no claims are accepted. Everything in the photos is included. If you would like the instruction manual, please let me know before shipping. 33
