the unit he got / some other unit the mseal in the first place was placed there to cover the exposed screw wherein another unit there is the tp-link sticker for same due to the condition mentioned as 5/5 at time of his purchasing he asked me to replace for this issue and I denied but offered him replacement at his own shipping cost because the product condition doesn't qualify as a replacement according to me but he denied spending any amount and along with some really rude conversations he threatened to get me banned if I don't do later after so much headache and locking horns with mods I have to refund him 200 to add in this I would like to tell that he bought the unit after a pathetic low negotiation
