I was drawn by the name of this brand " Love not war" and love its package as they are environmental friendly. When I first saw the collection, Koi caught my eyes the most, as it is a strong, coreless and palm size wand toy. I have been trying to find a portable coreless wand vibrator with a strong vibration for a while. Other wands which I have tried are coreless but their vibrations doesn't seem to be as strong. Another thing I love about Koi's wand its the size and shape of the vibrator's head. It a prefect size for the vulva. It's not too big and will not get into the way during couple play. Not only its great for situating the genital area, it also great for other body part as a massage to relax the muscle specially for the shoulder area. The only thing I wish this toy can improve is the battery can last a bit longer than 1hr.. ;)
