        I have used the Thunderbolt for two years and love it! I just ordered a new one. Three little things that I would change are, (1) make the Velcro to be a little bit longer on the belt because of weight fluctuations from summer to winter, etc. (2) the bottle caps will shatter if dropped with the liquid inside the bottle. (3) Offer an option to order BPA free bottles if desired. . on Jul 13th 2014

        Great belt three full bottles were too much for me but after drinking one half way through it balanced out overall a great belt and a great price on Dec 7th 2013

        I do love this belt but I wish the pocket was bigger as it doesn't fit everything I need. But it doesn't bunch and it doesn't move when I run! on Aug 14th 2013
