With my first baby I used an Elvie pump and as I no longer had it I wanted to purchase another wireless one for my second. I didn't want to spend a fortune so decided to try Wren as a more affordable alternative. I'm so glad I did, it is just as effective and a fraction of the cost. The only feature it doesn't have is the app but in my opinion sacrificing the app was worth the saving. When I encountered a small fault, customer services had dispatched a new part within an hour of my initial email and have been incredibly helpful since. I couldn't recommend the product or service highly enough. A wonderful small business, with a brilliant product that cares about its customers. Thank you!
