This one person tent is lightweight and easy to set up. It is also very nice that you can use just the rainfly and footprint as a lightweight shelter. The first few nights sleeping inside I felt a little cramped, but I got used to it. The tent is easily accessable through a relatively large side door. It also sets up very easily and adjustments are simple to make. One downside is that it isn't free standing, but it only requires two stakes; one at the head and one at the foot of the tent. I also noticed that even with the peak vent open, I still found some condensation on the top of my sleeping bag in the morning, a little better ventilation might be good, but the small amount of condensation is hardly a problem. Overall the tent is great if your ok with small spaces. It's weight and versatility are its two best qualities. I've used it on several trips now and of all my tents, this is my favorite.

I bought this tent looking for a lightweight shelter for (early) spring climbing trips in the Sierra, when I would prefer more protection from the elements than my tarp, which I use for summer and fall, could provide.

PROS:
-Lightweight for a 1 person shelter.
-Low profile keeps it steady during moderate to moderately-high winds.
-ease of setup.
-Cheap

CONS:
-At 6' tall, I'm quite cramped. Head hitting one end, feet the other.
-Difficult to change clothes inside.
-Tiny vestibule.
-Lots of condensation. which becomes a problem as I can't move within the tent without hitting the walls/ceiling.

If thinking of getting something this small, maybe just get a bivy and save even more weight...

The pros and cons listed by Cody are pretty spot on. I find getting dressed / changing clothes inside to be next to impossible, so I've had a few crisp mornings of getting dressed outside.

Despite this, I love my tent, and wouldn't trade it for anything. It's small enough that if you can lay down in a spot, you can set up the tent. I love that it's not a dome monstrosity. It's low to the ground, and with the rainfly on, it's a light tan color that isn't jarring. It looks like it belongs, as opposed to the typical neon bright colored tents.

When I'm laying inside, I find that I have enough room to move around and be comfortable. As mentioned, getting dressed is an issue, but I never feel clausterphobic inside. For me it was worth the investment.
