Everything about this is great. The only thing is that I have relatively small biceps (male), and I have to have this on the tightest it will go. If you're extremely skinny, you may not have enough slack on the velcro. Great to do business with!
Very secure fit on the band and Velcro. I had a knockoff brand only last a year, the Belkin one are still going strong 2 years in. I bought two more since the price was so good.
