Hey truckernix, did you mean that taking the cap off of the vibrator was hard? If so, then I must be lucky because it only took me about 2 minutes to get the cap off. I just took a hacksaw blade, cut at certain points along the crimp, and took the wire cutters/crimpers and spread the crimp. I now am left with the reusable shell and the inside of the vibrator, which has a foam insulator(?) over it. I need to know how to take it off without destroying/cutting it if it is possible.
