The Reuleaux RX200 is a hard-hitting, take-no-prisoners, mod that can keep on going when others have quit. The use of three (3!) 18650 batteries means that when you set this thing at 200W, you are going to get 200W each and every time until you get to around 10% left on the battery power, unlike the two battery mods out there that start to lose power as the batteries lose their charge.
It is very cheap to buy one at the wismec official authorized online store and if you buy it now, you can enjoy a 3% off more ,you can use the coupon "wismec" before March 31,2016 .
