I purchased this around June 2024 and used it for about 3 months. It's the same product as the one used at the maternity hospital, has few parts and an easy-to-wash design, and is made of heat-resistant glass, so it's durable and hygienic... I was just so relieved! Nipple x 1 (SS size) 100ml bottles x 2 I sterilized using the microwave disinfection method. Thank you.
