UV Sterilisers

Are they really a necessity? I’ve been thinking over the past few months if I should get one because part of me thinks it’s super pricey. Most of my girlfriends who just delivered a couple of months back have one and suggested that I get one for convenience. I need some serious evidence that it’s worth the purchase! And like other products, there’s a whole bunch of brands to choose from. I’m so helpless. 🥲 #FTM
