Sona is Lelo's redesign of the Womanizer products and they've improved several features. Sona provides different levels of pulsating air at the clitoral head resulting in a unique, intense, focused clitoral head stimulation. It feels like vibration, but the source is air pressure rather than a traditional vibrator push.
Sona's design is substantially different than the Womanizer Starlet and will appeal to differ preferences. Sona is much, much quieter whether pushed against a body or not. The controls are more elaborate and allow you to find the setting you enjoy and play only with intensity, or switch through different pulsation patterns. This means that you can wander around and experience different sensations more easily and don't have to cycle through the whole offering to get back to where you wanted to be.
Sona's shape is decidedly comfortable to hold in a variety of positions, and for people with grip strength problems the larger body is ideal. However, the size could be a problem with smaller hands. The pressure port is smaller by a bit in the Sona which might limit people who want to pulsate slightly larger areas. The whole body is coated with silicone or plastic which might add a measure of friction for grip.
Clitoral pumps are perfect stimulation toys for some, and a waste of money for others. If you like focused suction sensation over the head of the clitoris specifically, you might really enjoy spending some time with Sona.
