Greetings,
It's possible to get brand new units for this price, suggest you adjust accordingly - or is the price for both units?
Also, as you are a new member, can you post pics of the units & hashing proof with your user name, as well as info on where you are shipping from, local pickup availability & escrow acceptance? This will make selling your units easier, faster, less hassle and safer for the buyer as well as yourself.
Kind regards & Peace
