The camera is sound, with a one-day usage warranty. If anything is wrong with it, return it to me and I will refund you the full amount. I do not accept price haggling, and I do not permit or forgive it. I swear to God, I used it cleanly, I only took 10 videos with it. The 1TB memory is enough for you for 10 years. The reason for selling is the need for money.
