I don't claim to be an expert when it comes to tents but that one looks fine to me (unless your friend is planning an ascent of Everest!). It's reasonably lightweight, it's got a small pack size, it's the right shape for windy conditions and, most importantly, the 'hydrostatic head' figure (4000mm) is quite impressive. (i.e. the rain should stay outside the tent, rather than inside!).
I used to prepare teenagers for the Duke of Edinburgh's award scheme and I wouldn't have had any worries about sending them out on the moors with that tent as part of their equipment. (All the same, I still don't claim to be an 'expert'. If an experienced mountaineeer posts here, take his/her advice, not mine).
