There is a bit of a learning curve to setting this tarp up for us newbies, but once you've done it a few times you start to get the hang of it... no pun intended I haven't had any issues with getting wet or having buckles slip but I also haven't had any winds stronger than maybe 15mph either. But it is built very sturdy, although a little heavy also.
I will be upgrading in the next couple of months or so because I also have an issue with its size. There isn't a lot of room to store your pack, especially if you're hanging low. Which, because of the size of the DryFly, you pretty much have to in strong rain.
