This particular nipple shield is very hard to use, at least for a first-time breastfeeding mother. Within one use, my nipples got hurt and it should definitely be withdrawn, I have also contacted the company. Even level 1 is too strong. Having used 3 different nipple shields, this one is completely different.

I have had it for 3 months. The first time, within 2 weeks, the motor stopped working without any apparent reason. They replaced it. Within 2 and a half months, one of the two devices stopped suctioning (the tubes were not the problem). They replaced it, but not in a timely manner, so I was forced to buy the Medela. Overall, for its price, it is a good solution, but I would recommend it for occasional pumping. It has a slightly more complicated assembly and disassembly, especially when cleaning and sterilizing
