I bought these for my first 10K race, and I bought them particularly for the small pocket at the back for keys/phone/ipod. I'd barely paid for them before the seller had them sent to my door, so great fast service! I was a little dismayed however, when after the first use, the zip broke at the back. The seller contacted me, and when I mentioned the problem, immediately sent a replacement, without me even sending back the old pair. Again, I received them really quickly, and this pair has been fine.
The product itself - fits well, comfortable, does the job and at a very good price. The only reason it's 4 stars instead of 5 is because I think you need to be careful with the zip pocket. Other than that, spot on, and great helpful seller.
