2nd February, 2018 Buy Poi Pro Knob Retrofit Kit WT4 Handles "Excellent upgrade from my old PX3 handles. No more rope rubbing on fingers, good weight, silicon is much easier on your hands/arms/wrists when practicing tosses. Also have more control since it's easier to feel which way the tether is pointing. Highly recommend." Phil Keeling, New Zealand. [Verified Buyer] GOLD Member since Dec 2011
