The product is well made and efficient. High quality for the price. The pods or cartridges last long and are easy to replace. Shipping took 2 weeks, sadly. I learned that if while you charge the Phix to place the pods cover back on the pod, it will extend it's life span. Lessens the evaporation while the Phix is charging. After charging a couple times, while about a month it has become difficult to place the Phix into the charger to let it recharge. Like it will not fit, I have to apply pressure and fiddle with it. Also, juice or liquid from the pod will occasionally leak to where the Phix and the pod connect inside. It will create a burning taste. Simply use a Q-tip and clean out the debris. Good as new. Before placing a new pod into your Phix, it helps to do dry inhales to release the air bubbles that are caught in the cotton of the pod. This also help with any type of "burnt" taste. -Phix Review -Samantha R.
