Clitoral suction toys

Hello,

We are currently looking for a clitoral suction toy. We’ve tried (loosely speaking) 3–4 times, for 1–3 minutes each, using the Womanizer Pro40. My wife has said it feels weird and doesn’t really do anything. I’m not sure if it’s me or the device. I’ve been considering trying another one, but she’s unsure if the sensation would be any different. I’ve seen the Womanizer Premium 2, Satisfyer 2, and similar models. In your opinion, are we wasting our time, or could a different device provide a different experience than what we’ve had so far?
