Review on Nathan Handheld Water Bottle and Phone Case: Insulated 18 oz Flask with Convenient Hand Strap for Running/Walking. Hydration Pack for Runners with SpeedView Feature. by Bryan Gilliam

The water bottle itself is great but the rest of the product falls short of expectations. The phone section is outdated. It still includes a wired headphone jack (2011). It's too small for today's mobile phone standards. It doesn't have room for keys, gels, etc. It's not ported to deliver sound from speakers. The zipper isn't waterproof, so speaker holes shouldn't play a big role. The wrist strap is comfortable but very short-lived. The band is tightened with a reflective element that breaks very quickly, and you cannot attach it to your hand. The strap is also attached very cheaply with just a line. The bottle is loud. If you've ever heard a squirrel sound the alarm when a predator or danger is approaching, then you know the sound this bottle makes. It screams while sucking in air to fill the void you leave after drinking. The boost goes into the fray, it was probably a great product in 2012.
