Quoted from Master_of_Trolls:Were your Wizmods magnetic or a peel and stick (and, do they muffle the sound from the speakers)?
No peel to them. You just apply them directly to the speaker panel and the magnet grabs a hold. They come rolled up in a cardboard tube, so you may have to straighten them out a bit. The only manual thing you have to do is to remove the Stern identification plate before hand and then screw it back in afterwards. Also, the art covering the speaker panels have holes in them so the sound can travel thru.
Cool product. I bought a set for my Mando pin and hoping to get it this week. I went ahead and ordered (4) more sets for some of my other pins because I was impressed with the quality. The only bad thing is the shipping is free, but it can take a while to get there. It's a hit and miss. Been waiting for my last order over a month and a half now. It was shipped to Australia for some reason and I live in Indiana, so go figure.
Hope this helps.
