I borrowed one of their 30' domes for a local event, and was very pleased with it. It was sturdy and attractive, although the weather was very mild so I can't speak for its environmental abilities (protection from wind, rain, and extreme temperature). It went up relatively quickly and easily with 4 or 5 people.
Our camp has used a small dome form them for the past 4 or 5 years, and it has really survived well - no damage that I know of. Great in wind and rain. A bit hot in the daytime. Covering it with Mylar helps.
These domes are great. I had a 30' one last year that was 3 years old and it held up magically. I'm hoping to get a smaller one this year.
Things you might want to know:
-As with any structure, it is not really secure until the guy lines are tied. I found this one out the hard way, rookie-style.
-The site says you can put the big one together with 2 people in an hour. Try 3 people and 2 hrs. The smaller ones - 20' and under - can be put together by one person right quick.
-Wear gloves and boots when assembling/disassembling. The structure is tension-based and those pvc poles can pop right out and poke you.
-They are not totally waterproof. Keep some clamps and some drip cups on hand just in case.
and like MayaP said, it gets hot during the day. You can easily tie an extra tarp over it to create a pocket of cooler air and it should make it bearable during the day.
To get this post going again...yes, these domes are awesome. We've had one in our backyard for a few years now and it's held up great (just needs a scrubbing).
We are going to be reworking our yard and unfortunately the dome doesn't fit in with our plan so we're putting it up for sale.
Please send me a PM if you're interested. Must be able to pick it up...we're in the Boulder Creek area.
I have an 18' Playa Dome from them, and have no complaints (other than the fact that, if I got off my ass and fabricated one myself, it'd cost half as much).
