Query: extremely poor quality

I ordered two of these rafts for a trip to Mexico and did not even take them out of the packages until we arrived on vacation on 3/10/2012. I'm sorry I didn't - the rafts are of such poor quality that they are no more than useless. The valves are almost impossible to depress and neither will hold air for even more than an hour! I can almost understand having one raft that leaks but TWO????? What a waste of thirty dollars. I would recommend avoiding this product.
