They're great for what they are
If you're ordering these you know what there for.  They show soot/smoke when wiped against a wall or item very well.  They have a great consistency, and overall they do their job.<br />Pro Tip:  Cut them in pieces and only use a small piece per photo, or room for evidence.<br />Double Pro Tip:  Put those pieces in zip lock bags, tag them and hold on to them for awhile, just in case.
