hi, hope this helps: I took mine to the beach, and after each day before going to the hotel I cleaned it in salt water but re-wash it at the hotel. after the third day the on/off button became stuck, so I just took the battery off and left it in the bag until my return home. Once at home I dissaembled it in order to wash it in tap water and put some oil. Unfortunatelly the on/off micro-switch came appart and could not re-assemble it. First warning: before puling the board out, push the on/off button so it does not get stuck and break. Same thing while pushing it back in. Second warning: beware of the cable to the coil, it has to be re-inserted carefully so it does not block the LED. Now to the interesting part for you: The vibrator is just a micro-motor with an unbalanced weight, this weight can easily come off from the axis that holds it. I bet the vibrator still works, but shake it gently and you may notice something loose inside, it is not broken, just separated from the axis. I strongly suggest you to send it to GARRETT unless you want to deal with what I mentioned at the beginning. It will not cost you too much. My end of the story is that a technician replaced the micro-switch and carefully re-assembled the whole thing. Since I live in SouthAmerica, and for any Garrett repair I have to send the item to Germany (Garrett's policy), I took chances to repair it my way. You have it easy, so make your choice.
