Title: Common Sense Math
Review: This item contains inert gas which is heavier than oxygen.It creates a layer on top of the wine which prevents oxidation.You do not need to fill the bottle with the inert gas to prevent oxidation.Wine worth saving costs at least $15 a bottle.Assume it saves a half a bottle each time it is used. That is $7+ per use saved.If you use good sense and spray only what is necessary you can get many uses out of a bottle.Worst case, say it has 20 uses in it, that is 50 cents per use. Is there any more that needs to be said?
