Time for an update...
Finally got to really make use of the fly. It shrugged off morning moisture just fine and there was a distinct lack of condensate inside the top of the tent. However it was not so reflective that it lessened the heat inside during the day and the tent was very warm, more likely due to the dark blue sides as anything else. A shaded area or popup awning would be a better alternative to this fly for keeping the tent cooler inside during a hot sunny day, though the popup idea seems ironically redundant, lol. I have seen some other color Instant Tents with green or orange where mine is blue. Maybe those are cooler in the sun. I do like the way the fly just clips to the Instant Tent's exo-legs (or whatever you want to call them), just like the tent body does. But notice from my first picture that the fly covers the tent's tie-down points so I guess once the fly is clipped on you're supposed to use it for staking down, and not
in addition to the tent's stake lines... Of course I had already staked the the tent down before I fitted the fly, so whatever. Ease of setup is still definitely this tent's forte but I'll still say it would be worth a few $$ more to upgrade some of the quality aspects of the tent and include a full-coverage fly like the Aussie-market one.
I'm starting to see some corrosion on the inner leg supports. I guess they were still damp or there was some water in the bottom of the legs when the tent was last collapsed and packed away after a PINS trip. Nothing major, but I figure shooting some dry-lube down the legs will help out. Down the road I'm thinking the Instant Tent will get replaced with a Eureka Equinox 6 (
Eureka Equinox 6 Tent - Camping Tents) which looks similar in form and function to the Instant Tent, but it is even bigger, six-sided, and setup is more involved of course. Still, it has a serious-coverage rainfly, has stood up to pretty heavy winds in owner reviews, and some report having theirs for 10yrs or more. Obviously it costs 2.5-3 times more than the Instant Tent 6.
