Query: Really slippery!

I read all of the reviews for this product and was really excited to get a mat so I could stop using loaners and then it came and yes it smelled bad and I didn't really care but then I went to use it and it is ridiculously slippery. Someone mentioned that it was slightly slippery but in comparison to the loaner (maybe that was just a really good mat?) this was horrible. I could hardly stay in downward dog because my hands and feet kept slipping. So yes it's comfortable but who cares if you can't stay on it?
