Very true. I know that the Coleman tent will only last if I am careful with it, it is not really made for heavy duty use.
The Big Agnes may have cost 10x more than the Coleman, but I know it will, taken care of, last many, many years. Doesn't hurt that Big Agnes has excellent customer service and backs their products to the fullest.
I do see that with some of the cheaper tents that parents buy for Scouts, particularly in tearing them when being a bit enthusiastic about pulling on the tent corner rather than the stakes during take down.
