I've had my Zero for about 4 months now. It's a good device, I like it. Flavor can be hit or miss with pods at times. Sometimes the flavor is very vibrant with some pods, other times is more subdued...however it is consistent at least and the pods do last quite a bit before the flavor is completely dead. I actually just got a shipment of new pods today, so I'm hoping these newer ones are more flavorful than the old stock I had.
I do love the size and shape of it. I much prefer the short, stubby form in my pocket versus a taller device...with that said I always have it with me on work days.
