These are really good deals for the money. The double hammocks are appropriately sized but the mosquito ones are built for people no larger than 5ft 7in and most people buying these don't realize that. I know there are people taller than that always say it works fine for them but they are never experienced hangers. 10ft is considered the minimum standard for average height individuals and 11ft for people taller than 6ft. These come in at 8.75 feet.
This was my first hammock and at 6'2" I found it to be ok until I tried a 10ft hammock and realized how uncomfortable the woot one was. I found that to be great until I found an 11 ft hammock, which really is great. I gave this one to my buddy who is 5'7" and it works just fine for him.
There are threads about these exact hammocks on hammockforums (biggest and best hammock forum on the web) and it is unanimously agreed that these are 5'7" and under hammocks. I just wanted to put that warning out there to save some people taller than that some money.
