When I saw the design of this tent I couldn't resist trying one out. So I purchased one, and used it immediately with no prep. Took it out for a night on the Ocmulgee river in Georgia. It's pretty easy to set up, and fast even for just one person if you know how to do it. Even with a light rain and no prep, it worked fine and did not leak. I would recommend this as a ONE person tent. Yes, you can fit two people in it, however there won't be any room for gear. As a one person tent, it is SPACIOUS for such a small footprint.
Weight/Packability - It is what I would consider moderately lightweight for backpacking(<2lbs being ideal, >5lbs being unsuitable - it comes in around 4 lbs). The tent and rainfly can be rolled and put into a dry bag ending up about the size of half a football if done correctly (minus poles). This compressibility makes it ideal in my opinion for a good backpacking tent.
Internal Space - Ideally, its a one person tent. With one person there is plenty of space for a full hiking backpack, and whatever other gear you have. The shape of the footprint, allows you to put your gear beside you, instead of at one end making access easier in the night. I am 6'3" tall, and the tent is tall enough for me to sit up in it without bumping my head which gets it super bonus points. The gear pockets and loft placement is excellent, and nice for putting away small things like sunglasses, flashlight, or waterbottle.
Ventilation - Without the rainfly on, ventillation is SUPERB. With mesh over nearly the entire top half of the tent, it's perfect for summer months. With the rainfly on, it gets a bit warm inside during the summer months, unless you unzip and tie up the door mesh cover. In rain, it stays pretty comfortable inside with it all sealed up in any temperature. I'd say its multi-season, with either the addition or deletion of the rainfly.
Rain resistance - Obviously you should seam seal and treat the rainfly in any new tent purchase. However there are some really nice features for this tent. First off the rainfly covers the entire tent all the way to the ground, with the exception of the door. With waterproofing treatment, its gonna be extremely waterproof due to this design. The only weak spot would be the door. It is equipped with draft/rain collars around the zipper, so with proper treatment, it should not leak. I've had no problems even without treatment.
Ease of Use - The tent utilizes a two pole design. You insert the pole ends into grommets on the tabs from the base, and then using clips, raise the tent and clip to the poles. I've found that even for one person, you can have it up in 4 min or less. The rainfly simply hooks to plastic d-rings on the base tabs. If you want a more solid attachment, the rainfly also has tiedowns and velcro straps to ensure it stays put even in heavy winds.
Stakes - those horrid cheap bendable wire-bent stakes. Ditch em, and get some aluminum tri-stakes like the ones from coleman.
E-port - I'm not a big fan of the e-port. It was designed for use with an electrical corded device such as a fan or heater at a campground. If you spend most of your time in a campground, this might be a good feature for you. I however call it a "bug-port" because it makes absolutely no sense to mesh and seal up a tent bug proof, and then put a giant porthole on the side of the tent that allows them in. My suggestion: If you dont need it for electrical appliances, glue the thing shut. Its not a big deal though.
Overall, I'd highly recommend it for someone looking for a low-cost backpacking tent with high-end features for one person.
