Stella Beaute Hair Removal & Facial Device Purchased about 2-3 years ago. I've used it occasionally. There are no problems with the operation, but on the tray (the base), there's a disinfection sensor. When I opened the battery compartment, there was rust from the batteries (photo 4) and it's dirty. The part that you apply to your skin has wiring, so there's no problem, but the batteries in the tray (the base, which I replaced with new ones) I'm not sure if the disinfection is working. m(_ _)m The part you apply can still be used, so if you don't mind, please consider it. I haven't used it very often, so there are still 49,000 shots remaining out of 50,000. The power cord is also included. The instruction manual is missing. Thank you for looking.
