just tried my brand new lightforce suction bar with my new powabeam pro11. stuck the bar on and gave it a good few yanks and nearly dented the roof. pretty strong...so i thought. so off i go for a shine in the paddock, the light is fantastic then oops its let go and bang, dinged up spotlight!!! arghhh the spring flew off and lost the nut off the pivotal end. so my question is has anyone else had these dramas? cheers Mick
