I've read some great reviews for some of the more elaborate portable dome-tent products. Some of them look absolutely fantastic. However, I have heard some horror stories about delivery times (i.e. thousands of dollars prepaid only to see long delayed delivery of incomplete product and more delays in making it "right"). Also, while I find the idea of a fairly sophisticated portable tent dome attractive, I find it hard to believe the ad copy for some that suggests that the things can be put together in the dark with a pen light in 15 minutes. I read one ad that said "sets up easily in 20 minutes and packes neatly into 5 duffel bags . . . " FIVE duffel bags???? Sorry, but nothing that needs five duffel bags can be set up in 20 minutes. I can't get my kids' Winnie the Pooh play tent set up in my own backyard in 20 minutes let alone a dome tent the size of a small house. I haven't used one of these products so I can't really comment on them fairly. For me, there seems to be too much hassle, so I lost interest in getting one fairly quickly. However, if the cons associated with set up time at a site and a potentially long delivery time are not that big a deal to you one of the big high end dome tents could be fantastic.
