Is the Momcozy bottle washer worth it?

The only reason I don’t put bottles in the dishwasher is because they get pretty knackered looking quite quickly due to discolouration etc. I hand wash bottles then I chuck them in Tupperware with Milton sterilising fluid

For me, it’s nice to have a bottle dishwasher that I can use without having to unload or load 20+ other things. Plus other dishes may have bacteria from food scraps, raw meat juices, eggs, etc. I just don’t trust my main dishwasher that much - we often overfill and need to rerun loads to get them clean. It’s a mess.
