I purchased this new in July of last year. I opened the box to check the contents at the time of purchase, but I have never used the main unit or any of the accessories. I've been using another tent I bought at the same time, and I don't think I'll be using this one in the future, so I'm putting it up for sale. Since this is an unused item, please contact the manufacturer if there are any initial defects. Please understand that I cannot provide support. Please refrain from negotiating a price reduction.
