No bubbles when fermenting.

You're more likely to have to buy a new tube because you lose the tube somewhere in the brew shed than because it runs out.

You will also buy more brew stuff when you do replace it because shipping is more than the cost of lube and it just doesnt seem right to pay shipping just for a tube of lube.

I heard of a guy that did this..just sayin'

Slightly off topic but I just bough a bag of Maple Sugar for making bacon at home, cost was $12 and postage was $14 so I chucked in $40 worth of Dry Aging bags because it seemed criminal to purchase something for less than the cost of shipping it...
