Choosing a formula maker is a big decision, and if you’ve started researching you’ve almost certainly come across the same three names over and over: Minbie, Baby Brezza, and Tommee Tippee’s Perfect Prep Pro. All three promise to take the guesswork and middle-of-the-night faff out of making a bottle, but they go about it in genuinely different ways, and those differences matter more than the marketing on the box lets on.
We built Minbie, so we’re not going to pretend we’re neutral on which one we’d recommend. But we also know parents doing this research want facts they can actually check, not vague superlatives. So this guide sticks to the features that make a real difference day to day: how accurate the dispensing is, what the machine is made from, how it handles sterilised water, how much cleaning it creates, and how hands-off it actually is at 3am.
The quick answer
If precise, calibrated dispensing, minimal cleaning, and genuine set-and-forget convenience matter most to you, Minbie is the strongest all-round choice of the three. Tommee Tippee’s Perfect Prep Pro is worth considering if digital scale-based accuracy is your top priority and you don’t mind a two-step process. Baby Brezza suits parents who want the simplicity of a single dispensing station and don’t mind an approximate, scoop-based measure.
Here’s how they stack up feature by feature.
Minbie vs Baby Brezza vs Tommee Tippee at a glance

|---|---|---|---|
| Calibrated, precise dispensing | Yes | No, approximate | Yes, via built-in scales |
| Built-in kettle, water sterilised and ready | Yes | No | No |

Accuracy: does the machine actually know how much formula it’s dispensing?
This is the one parents worry about most, and reasonably so. Getting the ratio wrong consistently, even slightly, isn’t something you want to be guessing at every bottle.
Minbie is calibrated to your specific formula brand, so what it dispenses is matched to that formula’s actual scoop density rather than a generic average. You set it up once and every bottle after that is consistent.
Tommee Tippee’s Perfect Prep Pro genuinely deserves credit here too: it uses an onboard digital scale to weigh the powder as it dispenses, which is a legitimately accurate method and one of its strongest selling points.
Baby Brezza is the odd one out. It dispenses by volume using an auger system rather than weighing or calibrating to a specific formula, so the amount delivered is an approximation rather than a precise, repeatable measure.
Sterilised water: built-in kettle vs doing it yourself
This is where the day-to-day convenience gap really opens up.
Minbie has a built-in 1.5L glass kettle that boils and holds water at the right temperature, ready to dispense on demand. There’s no separate appliance, no transferring water across the kitchen, and no waiting for a kettle to boil while a baby cries.
Baby Brezza has no built-in kettle at all. You need to boil and cool water separately before loading it into the machine, which means an extra appliance and an extra step every time.
Tommee Tippee doesn’t have a built-in kettle either, though it takes a different approach to water safety: rather than storing a tank of pre-boiled water, the Perfect Prep Pro uses an antibacterial filter the water passes through on its way to the bottle. It’s a clever bit of engineering, but it still means there’s no reservoir of hot, ready-to-pour water sitting in the machine the way there is with Minbie, and some parents find the overall process slower than a true set-and-forget design.
What the machine is made from
Materials matter more than most people expect, especially for something that’s in contact with your baby’s milk multiple times a day.
Minbie uses stainless steel for its internal components, so there’s minimal plastic contact with the water and formula as they pass through the machine. Both Baby Brezza and Tommee Tippee rely on plastic parts internally, which some parents prefer to avoid for a feeding appliance used daily.
Cleaning and hygiene
Nobody wants another thing to scrub at 11pm, so this one is worth paying attention to.
Minbie and Tommee Tippee both use separate pathways for water and formula, which means less residue building up and build-up, and an easier clean overall compared with a design that funnels both through the same channel. Baby Brezza mixes formula and water through a shared funnel, which needs more frequent, more thorough cleaning to stay on top of residue.
One station vs moving the bottle
This is a small thing that becomes a big thing once you’re doing it several times a day on no sleep.
Minbie and Baby Brezza are both one-station machines: you put the bottle in one spot and it’s ready. Tommee Tippee requires moving the bottle between two points, one for the formula dispense and a separate step for the water, so it’s not quite the “set it and forget it” experience the other two offer.
Spill prevention
Minbie and Baby Brezza both automatically adjust to raise the bottle to the right height as it fills, which keeps spills to a minimum regardless of the bottle size you’re using. This isn’t a feature Tommee Tippee’s Perfect Prep Pro offers.
Which formula maker is right for you?
If you want the fewest extra appliances on your bench, the least cleaning, the most hands-off process, and parts that minimise plastic contact with your baby’s milk, Minbie is built around exactly that brief. If digital scale accuracy is non-negotiable for you and you don’t mind a two-step process without a built-in kettle, the Tommee Tippee Perfect Prep Pro is a reasonable alternative. If you want the simplest possible one-station machine and are comfortable with an approximate, non-calibrated measure, Baby Brezza is the most straightforward of the three, though it asks the most of you in terms of separate sterilising and cleaning.

Frequently asked questions
What is the most accurate formula maker?
Minbie and Tommee Tippee are both built for accuracy, Minbie through formula-specific calibration and Tommee Tippee through an onboard digital scale. Baby Brezza dispenses by volume rather than a calibrated or weighed measure, so it’s the least precise of the three.
Do I need a separate kettle with Baby Brezza or Tommee Tippee?
Baby Brezza has no built-in kettle, so you’ll need to boil and cool water separately before loading the machine. Tommee Tippee doesn’t have a built-in kettle either, though it uses an antibacterial filter system to treat water as it passes through rather than storing a batch of pre-boiled water, which is a different approach to the same problem. Minbie is the only one of the three with a built-in glass kettle that boils and holds water ready to dispense.
Is Minbie or Baby Brezza better?
Minbie offers calibrated dispensing, a built-in kettle, stainless steel internals and separate pathways for easier cleaning, all of which Baby Brezza lacks. Baby Brezza’s main advantage is its simple one-station design, which Minbie also offers.
Which formula maker is easiest to clean?
Minbie and Tommee Tippee both use separate pathways for water and formula, which cuts down on residue build-up. Baby Brezza’s shared funnel design needs more frequent, thorough cleaning.
