Portable Breast Pump Recommendations

Looking to replace my spectra S9+ to use in office as I find though suction is strong it is not so comfortable like the S1 which I use at home. And yield somehow is lower as well. Criteria is portable, light and relatively small and chargeable and gentle on nipples. I'm considering the below. Any reviews, especially if u have tried spectra S1 and can comment on how they compare would be great! 1. Cimilre F1 2. Cimilre S3 3. Real Bubee 4. Any other recommendation
