Start with daily bottle volume
A dedicated appliance makes more sense when bottles, nipples, caps, and pump parts pile up every day. Occasional use may be handled by simpler tools.
Drying is the real convenience upgrade
Sterilizing is only part of the routine. If wet parts clutter the counter or need to be ready quickly, a dryer combo can be worth comparing.
Check exact model capacity
Brand names cover multiple versions. Confirm bottle count, pump-part fit, drying modes, cycle time, and whether the model is sterilizer-only or includes drying.
Measure counter space
A useful appliance still needs a permanent place to live. If it has to be stored after every cycle, it may stop being convenient.
