    Bad quality

Flange broken after one week of use. Very disappointing !

### ⭐⭐⭐⭐⭐ 







  
  
    Wow!’
  

*by E***  on Reviewed in the United Kingdom on 22 October 2022*

My first day using these exactly the same as spectra but the tunnel is longer, the tubing is also longer which is so handy, I was using spectra’s 28mm flange with 19mm inserts so I brought these instead and I’m already seeing a difference In milk production because it’s so much more comfortable I should of purchased these a long time ago !
