I previously left a review stating that the vessel I received was defective and subsequently realized that it was a user error. However, I still would not recommend the company and most likely will not make an additional purchase once I finish the pods I bought. Instead of helping customers determine what went wrong, their customer service rep just acted like I must be intentionally lying to try to cheat them to get a new vessel that just cost a few dollars.
Bottom Line: No, I would not recommend this to a friend
I got tricked into buying the starter kit. Unfortunately, I ordered more than $35 worth of pods before finishing the 4th pod in the sample. After 3 uses, the piercer not longer sits in the right place; it keeps sinking further into the bottle when the pod is pressed onto it. So basically the pod cannot be pierced open. When I contacted customer service, the rep insisted that their vessel was not defective and claimed that the vessel is out of stock when they are still selling the starter kit online. She also refused to let me return pods that were just delivered. So I just wasted all the money for the starter kit and the pods and was left with a bottle that's going to trash when I could have used that to buy lots and lots of soft drinks or bottled water.
