Review on Black Hydrapak Blaster BITE Valve with 1/4-Inch Inner Diameter (I.D.) by Trae Joubert

I used this to replace a leaking bite valve on my standard 2 liter Nathan bottle. Switching was easy, taking a few seconds and a twist of the wrist. Fits perfectly. The flow of the liquid is good, it doesn't drip before the bite at all. The lid (removable) and swivel mechanism are nice improvements over the standard version. I've only used it for a few weeks so durability isn't listed, but for a few bucks it extended the life of the inflatable tube, which was fine except for the valve.
