Query: Broke in 1 week, got replacement, broke again in 1 day

I purchased this DVD player, and after using it for 2 hours a day, for 1 week, it stopped working. I contacted Coby and was advised that I had to pay $18, even though the product has a 90 day warranty. I sent the DVD to them anyway, with the $[...] money order. I received a brand new , sealed, same model back, and this time it stopped working after just 1 day of playing DVDs. The same problem as the 1st one, it just stop reading disks. Do not buy this product, it is JUNK.
