Query: Not for the real runner

I could not believe it when I saw this in my "recommended for you" file! I bought one of these about 18 months ago and I am done with it.Now I run 5 days a week, usually for an hour or more. 30 to 50 miles a week. I use the arm band during warm weather when I don't wear a jacket. About 6 months ago it started slipping a bit and I would have to tighten it a time or two during a run. The velcro is just too cheap. Since the weather got warm here this spring, it's almost useless. It won't stay on at all. Nothing beats running a race carrying your ipod!This is not for the serious runner, or for anyone who has the expectation of it lasting for more than a year. There has got to be something better out there! And I'm going to find it!
