I loved this battery. Thin and portable, I only used it an average of once a week, but it went with me everywhere in a pocket of my handbag in case I needed it. Then after six months, the attached cord stopped working. I informed the company by text and they not only replied within 24 hrs, they shipped me a new one free of charge, which arrived a mere 3 days later. With so much dishonesty these days, it is wonderful to find a company with conscience and integrity.
