Great product and gets the job done and then some! Some vibrations are not so quiet, so if you don't live alone and walls are thin, maybe it can be heard? Haha. Other than that, so far it's been good.
I am loving my Lelo Sona! I literally use it everyday because it is so powerful and has so many modes that fit my playful mood. I am obsessed with the design and the color as well.
It is waterproof, very durable and has a long battery life. I use it for hours every night and can last for days without charging.
