First let me say we love our system. We use our Coravin at our restaurant, and it allows us to offer rare and more expensive wines by the glass which pleases our customers greatly!! With regards to restaurant service, it would be great if there where some way to have it do a measured amount rather than a random pour. Our only problem with the system is that the capsules are such a waste. We liken them to plastic water bottles or k-cups. If the capsules were re-fillable the unit would be a 5 Star winner in our book. At the very least if they were recyclable...that might help, but still a HUGE waste of resources. Seems like with all the engineering involved in this unit, that was a huge oversight. Though I imagine that was because you want to sell more gas capsules, though you could just sell the refill size unit of the capsules. Either way, it is a travesty and definitely prevents us from using it more than we would like to.
Since purchasing the Faster Pour Needle, I have had nothing but problems with my Coravin. I have already went through two capsules and only got two glasses of wine from each capsule. I never had this problem when I used the standard needle. I will be going back to the standard pour needle. Do not waste your money!
