User Review: Eureka! Tetragon 9
Design: three-season freestanding dome
Ease of Setup: pretty easy for two people.
Weight: 11 lbs.
Price Paid: $125
It's ok, but i wouldn't buy another one. As first time campers, we appreciated the space and ease of set-up. But the poles are garbage.
After the first use, I had to replace both canopy poles and one of the main poles. During a windy rainstorm, we got wet because of a poor design. I now realize a full-size fly is best. In the end, you get what you pay for.
