KandyPens Rubi vs Pax Era vs Juul

All three devices are among the best in their category, but the Rubi is the clear winner here. It is the most versatile of the three and it has the largest battery capacity. The only negative is that its refillable pod isn’t as convenient to use as the disposable pods found in the other devices. However, that is a small price to pay when you consider all the other advantages the Rubi has over its rivals.
