I purchased the WE Dart UL sometime late 2011. Since then, I've taken it on several trips, one being the South Coast and another being Frenchmans Cap. It was used on both trips fairly heavily (I spent one night in Vera Hut on the return leg).
It is described as a 1.5 man tent. The reason I bought it in particular is so I can store all my gear in it - bag, jacket and other wet gear in the outer vestibule and the rest inside. I spend some time traveling around foreign cities and I needed a place to keep my gear safe-ish when inhabiting a random park or popular campsite. Also, I am a bit pedantic when it comes to leaving gear outside when I'm on a tramp. In most wet situations I wring a tarp up which allows me to do all my cooking and faffing about with gear without things getting absolutely soaked. I'm about 184 cm and I have a minor problem sitting upright, although without a camping map I can sit without my head touching the roof. Nevertheless, I'm mostly lying down or crouched over the Trangia which fits nicely in the outer vestibule when the weather comes in hard. Should a situation where two people need to inhabit the Dart, top-and-tail would be comfortable enough for a night or two.
The outer canopy has proved to be excellent with heavy rains and beads quite nicely. A month more or so of rain will tell the true ability of the waterproofing, I imagine. The seams seem well made. I have noticed the fly zip gets caught on the storm flap if care is not taken, which proves to be a problem in instances when the fly must be closed quickly. The tent props up with no signs of "corrugation" i.e the outer canopy feels springy and taught.
The inner canopy is almost fully mesh and coupled with the two ventilation panels allows for good airflow (something I have really appreciated, being a hot sleeper). The fly may be pitched individually, which I have not tried but seems to be an appropriate solution when the weather is good and minor sheltering is required.
The poles which are in a cross-over formation set-up very quickly and require one person and about two minutes. There is a third, smaller pole that attaches perpendicular over the two which allows the tent to be completely free standing. Handy when pitching on sand or over pebbled areas. Guy ropes are solidly attached to outer canopy and are not necessary unless in exposed areas with high wind.
At about 2kg, it's a tad heavy, but I consider the benefits as being worth an extra few hundred grams. I noticed Passion 8 (here in Hobart) had them quite cheap on sale a month or two ago - rivaling most internet prices at about $300-$400.
I hope this has been of some use to those who are interested, and those who plan to buy. Please sing out if you have any particular questions or reviews of your own, as I realize this is not a fully-comprehensive review and is tailored to my particular use of the tent.
