I purchased and used this in July of this year, but I am selling it because I received a different model. It was stable during use and I had no particular problems with it. It has been updated to the latest firmware as of now. It is in good condition with no noticeable scratches, but please refrain from purchasing if you are concerned about it being a used item. Thank you.
