I recently bought my pair of Wren wearable breast pumps and am absolutely delighted with them! I had used another brand of wearable pump for about 8 months and found that it was prone to leaking. The wren pump in contrast is really well designed and I haven't had any leaks yet after 3 or so weeks of using them daily. They are sophisticated enough to get plenty of milk in each session, yet very easy to use. The only potentially negative comment is they aren't silent, but that wasn't a priority for me. I'm really pleased to have got them just before returning to work, as I know I'll have reliable pumps that won't leak through my work clothes. Thanks Wren - very happy customer!
