I'm a bit G-spot fixated at the moment, I love experimenting with new toys and sharing my newly gained knowledge with my glamourous assistant...aka my hairier other half, who is my biggest turn on yet.
These batteries seem to last ages compared to some of the cheaper varieties, I haven't carried out a systematic experiment on this so it could just be that I have been influenced by clever marketing, however the vibes I have running on these last a long time with regular use. Good value for money.
