I just got one today. Just over a week from Oz to NY. It plugs right in and worked as advertised. It was taking and giving hits within minutes of opening the envelope. I put it in my new HL StuG III G. It's already IR. THe only downside is it registers hits by spazing out. I wish I got the $15 2nd board which gets rid of the track recoil and slows the tank down with damage (As is, it only shakes until it's destroyed). The only problem I've had was the HL and my M4 are on the same frequency, so until I get a new crystal, I can't use it with both Tamiyas (I have 2 sons, hence the need for 3 battling tanks).

I have a DBU package with sound on the way to compare, which will go in a HL Pz IV that's enroute.
