Worth it. Fits a lot of bottles and parts. Compatible with all brand bottles- I have Tommy tippie , dr brown , Phillips and motif breast pump parts. Sterilized and dried in 45 minutes. No need to put the sterilized bottles on the mat to dry unlike some other sterilizer I bought earlier. Does take up space but looks better than the rectangular design. I use it everyday and am happy with the purchase. If only these units could wash the bottles as well.
