I have two - long story but after reading all the posts about broken raiders, I thought I'd buy a backup. so I now have a raider and a glomex 1.5m whippy thing. http://www.glomex.it/details.asp?idprod=RA112
Having said that the raider has been modified from the original design - the newer ones have the plastic of the base runs a good few inches up the antenna part, presumably to give the joint a bit better support, mine has meet the garage door on a couple of early mornings and has had the plastic thing i described above slightly modified with Sikaflex....... I can't say I've noticed a spectacular difference in reception quality between the two, even though the raider has been properly mashed.
I swap them over every couple of months just to make sure they both still work, and so far they've both survived 2 seasons
