Product review (2 stars): Product not as advertised!
I.D. is 1/4" NOT 1/2"I.D. as advertised.  This affects the performance in terms of how fast the machines will fill. I ordered these based on this specification of a 1/2" I.D.  Otherwise they are as stated, however, this is a big misrepresentation of the product as they are half the capacity stated.
