These gliders are easy to put together and pretty rugged. The seller requested this review which might have been better but if anyone is this desperate to get a review three stars is the best they get. They look nice and are rugged, the only problem is they don't fly well. Why go through the trouble of designing a product, packaging it, marketing it, but never opening the package to see if it flies is ridiculous. OK they fly a little but so does a piece of trash when you throw it.
