Are you looking for a vibrating panty or just a regular vibrator? If the panty is what you are looking at, I suggest reading the reviews listed on it-Astrea Reviews
. But if what you are looking for is an actual vibrator you could try typing in the search bar for 4 or 5 vrooms( that will show you powerful ones ) You may just have to search the really powerful one to find out which ones are the quietest. If you need any other help you can message me anytime.
