Cheap tents: wait for the first breath of wind 😐
We bought a Gelert four man tent (wasn't even that cheap) and used it about four times in the first year – always in nice summer weather. Took it car-camping up Sutherland / Assynt way a week or so back and it fell over in the middle of the night. It was blowing a light wind.
Upon closer inspection in the morning, three of the fibreglass poles had splintered along their full length and loads of stitching had given way, both on the inner and outer.
In future, I'll only buy super-cheap tents on the basis that they'll need replacing every season, or use my tiny wee expensive tents and cook in the rain.
