Review on 💧 J.CARP Bite Valve Tube Nozzle Replacement with On-Off Switch for Water Bladder by Predrag Hall

Disappointing. Only one of the four bite valves works. The other three do not open when the valve is squeezed or bitten. I could enlarge the holes with a sharp knife, but I don't have to. Also, the yellow switch on the rectangular flow valve is very difficult to move with two hands, let alone a finger like Camelbak's original product. I will be returning this package and will not buy from this seller again.
