Sandbag query

[Over Open Sights]

Greetings all. Have any of us used the "flexible sandbags" produced by Greenstuff World? Are they worth the money in terms of use and end result or do I stick to making sandbags out of Milliput? Here is a link to said material on Ebay:

Can't say.

I know people use milliput, and/or clay, and then press a piece of gauze, or other, small detailed, textured fabric into the stuff to get a pattern on it, in some scales, and then let air-dry.  Dry-brushing looks great on them, in some scales.
