I bought a Six Moon Designs Lunar Solo (e) in June of 2007 and used it through two backpacking seasons.
First of all, I need to point out that my Labrador retriever backpacks with me (he's part of my sleep system!). While he fits quite well curled up in the triangular area of the LS meant for one's pack (I use my pack as my pillow), this tent was designed for one human, without canine companion. In other words, I was stretching the envelope a bit.
In 2007 all our trips were in fair and dry weather. We were in the tent only to sleep, and the LS worked fine for that. I really enjoyed the light weight and compact footprint of this tent.
In 2008 I took two one-week trips in the Rockies. On the first trip it rained every day, with several severe thunderstorms (think cloudbursts, with hail) starting about 5-6 pm. The dog and I were confined to the tent for several hours before bedtime. Under these conditions, the tent was just too cramped! We also suffered significant condensation problems, not surprising considering the weather and that the tent's ventilation system was built for one human without dog. We also had significant condensation problems in fair weather on the second trip, during which it froze every night. If I woke up before the dog and wiped down the inner surface of the tent (really easy to do in that small a tent), we were fine. If the dog woke up first and started his whole-body-tail-wag routine, it created a monsoon inside!
A second problem is that I use a 2.5" insulated air mattress and high pillow, which gave me more chance to brush against the head of the tent, even when guyed out.
The condensation problem, however, wasn't just due to the dog. During a family trip, without dog, to the damp and drizzly Olympic NP wilderness coast, I slept alone in my LS. I had significant condensation in the tent every morning. My son and his two children, who slept in a Tarptent Rainshadow 2 right next to me, didn't have a drop of condensation inside. My tent before the LS was a Tarptent Squall 2; the dog and I had no problems there, either, even in soggy weather. I believe the Lunar Solo could use a larger peak vent. The considerable amount of canopy outside the netting wall definitely collected moisture from the ground--I would see condensation there at bedtime--and funneled it into the tent.
So three caveats about the Lunar Solo: First, it's for one human only; if you have a dog get something bigger. Second, it will get more condensation inside than tunnel-shaped tents like Tarptent's Squall and Rainshadow. Third, if you have a thick sleeping pad and like a high pillow, you have to be more careful about not brushing your head against the tent wall. I'm only 5'3"; I don't think this tent would work for someone a foot taller.
On the other hand, this tent stood up really well to the Labrador tail wag (he can clear books off a coffee table with a single wag), to running kids and dog tripping over the front guyline, to me tripping over the front guyline in the dark (unfortunately, the guyline is black), to the Colorado cloudbursts and to the high winds that came with them. It is not, as one reviewer suggested, fragile! The only time I ever had a pulled stake (even in ground where I could get them in only halfway) was when I tripped over the front guyline at night. I suggest replacing the black front guyline with Kelty Triptease (it's the right thickness) or similar reflective cord.
I have sold my Lunar Solo and gone back to my Tarptent Squall 2. I have fond memories of the LS, though, and especially miss the zippered vestibule and the lighter weight!
If it hadn't been for the condensation I had on the Olympic coast, without dog, compared to the Tarptent pitched alongisde it, and the invisible (in the dark) front guyline, I'd give the Lunar Solo a 5++.
