Query: Not bad, but not really what was advertised.

I received these balls today and they were shipped quickly and on time. Most of the balls are in pretty good condition with only a few (6) discoloured or roughed up. The main reason for my disappointment is that 10 of the 36 ball were the older HX Bite and not the HX Hot Bite I was promised. You may think I am being pedantic, but the reason I bought these was because I knew the Hot Bites were relatively new and would be more likely to be in a good condition. My fears were confirmed when I looked at the HX bites and discovered that all of the discoloured balls or rough edged balls were in fact the HX bites and not the HX Hot Bites, which were in far better condition. I still think these are a pretty good deal for the price, I just don't like being sold something different from that which is advertised, especially if it means the quality of the product is lowered.
