Bests & Worsts Reviews from Amazon

This is our 5th tent in about 4 years, going bigger as more of the kids reach camping age. This is the 3rd "Coleman" I've bought, and I put that in quotes because I think this one is a cheap knock-off. The previous 2 Coleman tents have been durable and held up to all the kids could dish out with no major damage. This one had one of the 4 critical ring tabs rip off as soon as I put in the support poles- pic1. The main pole support sleeve was poorly sewn and started tearing loose as soon as there was tension in the pole from the bend- pic2. The blood on my fingers in pic2 is from getting caught by the plastic clip at one of the metal pole fittings and taking out a chunk of skin. Two of the guy-lines for the rain fly poped off when the seams failed in the plastic rings, one immediately while assembling and one during the night- pic3. The zipper for the main door was barely functional and "jumped teeth" in several places, but I didn't get pics. The seam holding the door flap was particularly bad, was not reinforced, and was coming undone before the tent was even up- pic4. My feel is that this was a knock-off, I hope Coleman would not really sell something so blatantly bad under their name. Coleman, any response in your defense? I'd like to hear back. Any way to ID if this is a knockoff?
