Cons:
-the instructions behind the product forgot tom mention the TRICk to open.
When you insert the needle throw the cork, you have to pump air and give little torsions with the dispositive to move cork.
If you only blows you won't move the cork. The pressure is insuficient to remove the cork. You have to give this "help"!
Other Thoughts:
-the instructions could be better
-the box of the product is little ugly for gift...could be better...
