This glider, which was pretty expensive (over $20 in US), could stand some design improvements.
1) The post which holds the front of the wing in place (as well as the thingy cover) broke after about 2 flights (in which the thingy cover was opened/closed several times to re-weight the glider). A screw was used to replace it (required drilling). SUGGESTION: use a screw in place of the plastic post. A screw like the one which secures the thingy cover would not add much weight and would be much more durable.
2) The wing leading edge broke on about the 15th flight. Upon inspection, the carbon fiber rod appears to have no longitudinal strengthening...it's just carbon fiber rod. This will prove difficult to fix, as it's buried inside the wing and there appears to be no way to fix without un-sewing the wing material. SUGGESTION: This thin carbon-fiber rod could benefit from the inclusion of a structural thread (or two, or three) impregnated...to provide some lateral strength.
