Was the Storm 200+ new? As some one might have pulled a fast one by ordering a Spirit 200+ swapping it for their Storm 200+ and then returning it. The retailer then didn't check so didn't realise they had been scammed and then sent it out to you when you ordered a Spirit 200+. It happens quite a lot on Amazon. Just saw a video this week where some one ordered a Canon 1D Mk 4 over $5000 with other Canon Pro lenses, but what came was a very light camera box, seal broken and clearly what should have been a brand new camera and all associated docs, leads, etc was in fact all a mess and a really old Canon Ti Rebel camera and crappy kit lens!!! Suffice to say the guy was not happy or impressed. Fortunately Amazon dealt with it swiftly and send him another and he returned the pile of junk that some one had scammed Amazon with. Where the scam actually happened is anyone's guess. Inside Amazon itself, dispatch, courier ......... any one's guess.
Anyway the tent you actually have might actually be a better one than the Spirit 200+ as I remember looking at this one for a short time because of the large porch but decided against as it was just too heavy. I saw a Vango Force 10 storm tent a couple of weeks ago whilst camping in Wales and I have to say I was impressed. Fully Geodesic and very light and quite expensive looking as well. Whether your Storm 200+ was a forebear I don't know but I think it is probably a better tent than the Spirit range which I think are now discontinued anyway, but maybe wrong. Vango do some good budget conscious tents. I have a Mirage 200 which is self supporting and I like but it's a bit heavy. But now I have MSR tents which are fully self supporting and so easy and quick to put up and take down. My pick is the MSR Elixir 2. Great for cycle touring, plenty of space, two doors and two large porches to store panniers and gear. Can pitch inner first or fly if raining, can pitch inner only and sleep under the stars if that's what you want to do on a fine warm night. Highly recommended.
