Niah "It's very quiet, and it's not multi-speed. Again, if you put the batteries in, that's the way it's going to vibrate until you take it out. Maybe mine was defective, I don't know." I found that this happens when the plastic insert is not inside it. Niah "Well it DOES have a turnable switch for on/off, but mine was on as soon as you put the batteries in, and the dial doesn't work." The on/off switch also only works when the plastic insert is inside it. These were all things I have discovered. Here is a copy of the email I sent to the customer service. "I ordered the magic bunny stimulator with 2 day shipping. The product was great for the first 5 minutes. It gave an awesome strength of vibration. Then it slowed down. A minute later it died. After a few minutes of rest, it regained its strength but completely died less than a minute later. I decided the batteries were bad, so i went and bought more. I replaced the batteries and once again had the great vibration. This only lasted for about 15 minutes. It slowed down and a few minutes later it died. After much testing of theories, I think i have found the answer. The batteries seem to get EXTREMELY hot. When this happens they slow down and then stop. Once the batteries cool off for a few minutes, the bunny works like wow again. I feel this is a problem because my girlfriend, and i imagine most others, can't get full pleasure in that short amount of playtime." I think this answers all the questions. Like it says, it has the greatest vibration in the beginning. My problem is simple. My girlfriend has a low sex drive. She LOVED the beginning vibration and it is the strongest I have seen. But once it slows down, so does her pleasure. Help if you can, please. I'm not trying to drive people away, I just want some help.
