Is a bottle sterilizer a must have on your registry or in your house?

So, I keep getting offered a bottle sanitizer from a family member, but I’m not sure if I’d use it enough to warrant the space it would take up on my kitchen counter. The bottles we have are dish washer safe, and our dishwasher has a sanitizing setting so I was just curious what everyone else thought? Was it a super helpful item in your house or not really needed?
