I ordered this item, but did not get notified that it was delayed in shipping. I was upset because this was a birthday present for my son and was now going to be late. When I contacted the seller about this, they more than compensated me for the mixup and delay, and my son was SO EXCITED to get an upgraded version, even if it was late. This made me the #1 Mom in his eyes!! I really appreciate what the seller did to help make this right!!! They are very serious about 100% customer satisfaction, they know their products, and they are great to work with. The product is also top notch!
