I've been using this for about six months, but I no longer need it due to a change in environment, so I'm selling it. There are some minor scratches, but it works perfectly fine. Please understand that this is a used item. I will take measures to prevent water damage, wrap it in bubble wrap, and ship it via Yu-Packet Post Mini.
