my son put them on his ute and he asked me how do ya know if they work? well i said if nothing jumps out in front of you they must work but if you hit a roo take them back and get your money back. is there a proven method ?

I had a mate down on Eyre Peninsular who swore by them. Rode for farking thousands of ks and never hit anything.......until he hit a bloody big roo outside Broken Hill. Busted his ankle and didn't do much for his Heritage either.

They do absolutely FARK ALL! Just keep ya eyes open. I'm used to riding where camels, buffalo, roos, eagles and all sorts of bluddy big lizards live and I've never hit one.

They only work when it's daylight saving, so you have wasted your money Flan.

I need one ,,, Hit my second Kangaroo in 6 months, Im getting sick of it now. It dosn't look like much damage, but the Radiator Suport Panel has been pushed back about 4 inches down the bottom.

I have found to work very well up this way

 

I did the same Flan and got laughed at,,,lost one already,,,no Roos hit though ...still not many in the Dandenong ranges (I hope)........
