Top line: Comfortable belt that safely contains your phone and more, providing easy access (just not while on the move!)

Good: This belt is very comfortable, provided you can find the right size (try on at an expo or sporting good store if you have an opportunity). It has really good stretch, and can accommodate almost any size phone (XLs might be too big--check the answers here for verification). GUs, cards, etc. all fit with ease, though I wouldn't recommend for a hard water bottle (I have not tried the Flip Belt custom waterbottle). The clip, though a small feature, is nice for locking down keys and giving extra peace of mind that they'll still be with you at the end of the run.

Bad: Don't expect to go into it for your phone while on the run, unless you are willing to stop. One you start to sweat or the belt gets wet (note: NOT waterproof), taking your phone out is about as much fun as putting on a wet t-shirt. It arguably has **too many** pockets/slits, as I'd love to have a longer pocket with less potential of something falling/poking out. Also, the second belt I bought had serious durability issues, and the seams came apart in less than a few months of use. Meanwhile, the first belt I've have and used for over 2 years with literally zero problems.

Other: I have found that the optimal location for this belt, especially if carrying a 5"+ smartphone, is near the small of your back, right above your butt. You can wear it in front, but it is more noticeable on the move and more prone to jostling. Second, if you have wide hips and a small waist, the belt may be prone to the dreaded "ride up" phenomenon. Most of this is based on hearsay from my wife, so YMMV.
