4LR44 Batteries

These actually last way longer than the ones I was using before, which is a relief since I hate swapping them out mid-use. Being child-safe is a nice bonus too.

I was skeptical about the "longer-lasting" claim, but these have genuinely outlasted the generic ones I used to grab. They fit my bullet vibe perfectly and I haven't had to swap them out nearly as often.

These actually last way longer than the ones I was swapping out every couple weeks. Nice that they're child-safe too, one less thing to worry about with little hands around the house.
