It’s childish product. I see 2 main issues with it: 1. The item is not vacuumed to the table, because of that you need to hold it while using. 2. In order to avoid losing all the drink gases you should drink the all bottle at that time (because if you want the drink to flow, you need to punch a hole using a pin they attached to the item).
Poor quality - water everywhere. Product does not work properly. Disapointed!
