Apparently it's been so successful at drawing missile fire that Ukraine is ramping up production.

Now for a story being reported by the Washington Post - that Ukraine has been using wooden decoys of US long-range rocket systems.
Why? To deceive Russia into wasting expensive missiles on fake targets, the paper says.
It can be very hard to distinguish between the fakes and the real US-made High Mobility Artillery Rocket System (Himars) when viewed through a Russian drone camera from a distance, Ukrainian officials have told the US newspaper.
The importance of the advanced missile systems to the battle in the south and east means Russian forces view them as vital targets to strike.
It's led to Russian drone operators giving the locations of the decoys to cruise missile ships in the Black Sea, the Post says.
The wooden replicas have drawn at least 10 long-range Kalibr missiles after just a few weeks in operation and their success means production has been expanded, Ukrainian officials tell the paper.
The Washington Post adds the replica's destruction could partially explain Russias "unusually boastful" claims to have destroyed many Western artillery systems.
"Theyve claimed to have hit more Himars than we have even sent," one US diplomat notes.
