On the Orange Spectrums I have been lucky with the 6 channel and I have three of them .The reviews on the 9 are really bad !!
I am thinking that there was a bad batch because it seems like so many were happy and then bam, a bad batch .
Feel free to pm me but my results are all on the 6 channel .

As far as location and name , yep , all the same and I know at one time they were differant , I think they combined to one location but they have always been related as one company (differant family members )
