Weber Gas bottles protective cover 5 KG 2012

After reading the reviews I had my doubts whether I should order this protective cover for the described fitting inaccuracy.
But as the recent review was from November 2011, and to me the product heading "Weber Gas bottles protective cover 5 KG 2012" suggested that it would be here with a new model from 2012, in which the fit is possibly improved, have I bought the part and behold Reingefallen!
The quality of the cover is not to be criticized, but the fit is still "appalling".
If the manufacturer's really not bad products, sold for good money on the German market, it should also be based on the local standards.
The seller should remove the product definition the year 2012 do not mean more customers that in this model may be the fit was improved. Or is that something like this intentionally?
