Absolutely fantastic bit of kit. SO glad I went with Wren over other leading brands. Basically the same pump for a fraction of the price. The suction is SO good and I find I actually get more off with these than I do my plug in medela swing flex which was always my go to before! Now I just pop both of the Wren pumps into my bra and carry on with my day. It’s honestly life changing not being strapped to a plug! I would say these are one of the best baby purchases I’ve made. They’ve been an absolute lifesaver! If you’re on the fence, don’t be. Just get them. I promise you it’s worth every single penny!
