The buttons on the Reauleaux DNA 200 are rattle-free and super clicky. On the front, there’s a USB port for battery charging and to update firmware. The mini screen menu displays battery level, resistance, voltage, temperature and wattage. Wattage is adjustable in increments of 0.1W and power level can be locked. Up to 8 custom profile settings can be saved using Escribe desktop software. At $214.90 , the Reauleaux DNA 200 is a steal. As far as DNA 200 box mods is concerned, this one is said to be one of the best.
