Dude don't bump after half an hour, it aint gonna do you any favours with admin and mods or make people reply any quicker!
If you want my opinion, which I was going to give regardless, I think they are the best thing ever.. for making your car look like it's owned by a chav (assuming you mean the little things that raise the bonnet slightly?) I'm sure they have some purpose if you're running something serious under the bonnet, but I really really don't like them otherwise. That's my personal opinion though, if you like them - go for them.
