Admittedly, I never tried the Ina 1.0, but the Ina 2 was my best friend for 3.5 weeks on the road! Super strong simultaneously stimulation and g-spot, waterproof, rechargeable and lockable for travel, this is the first rabbit that's really pleased me. I think it would be suitable for many body types with a wide range of vibration speeds and patterns and an adjustable shaft that's not too big or small.
