Unusable

[This review was collected as part of a promotion.] Bought this last summer for use this summer in the Boundary Waters Canoe Area. Thank goodness I tried it at home before lugging it up there. The tension of the legs causes the top to pop off, making the product unstable and unusable. Too bad; its lightweight, has a great carrying bag and would be a good-sized surface area for games and drinks if it would just stay put.
