Purchased to minimise weight. Quick and easy to pitch, and pegs work well in tough rocky ground (to prolong life groundsheet would benefit from protection). Cosy for two as you would expect,but not too tight - but difficult to avoid pushing inner against outer when moving around. Not great ventilation, and under clear skies condensation collects on fly even with door open. Water permeated through grounsheet underneath sleeping mats when a lot of water pooled underneath, but yet to test on just wet ground, or strong winds.
I made three small modifications. Firstly, I shorten the pole, because it is too tight to insert. I don't think female or male in a cold environment can insert and fix the pole. Secondly, I fixed two end poles by epoxi, because they need not to be separated. The same size in the stuff sack. Thirdly, I add two tensioners for each end guy lines, because when there are rocks at the stake place, they need to be adjusted the length. After those modifications, Robens Buzzard UL is became perfect for me.
