The Boon Orb is, indeed, a compact, warmer which we found had a tendency to overheat milk in our testing. We also found that the time spent setting up the warmer for every single use took away from overall warming efficiency. While inexpensive, we recommend budget-minded parents set your sights instead on the Best Value award winning Chicco NaturalFit, or the Editors' Choice Kiinde Kozi.

Our Analysis and Test Results
The Boon Orb utilizes steam heat to warm milk quickly. It has an auto shut-off function with a small light on its simple control button. Though compatible with standard narrow bottles, it only fits select wide bottles like the Playtex Nurser and Munchkin Latch. A big issue with this warmer as well is that it can not be used with glass bottles; the steam gets so hot so quick that the rapid change in temperature may break glass.
Health and Safety
Ease of Use
The Boon scored a 3 of 10 in ease of use, the lowest scoring warmer in this metric. While the initial setup of the warmer is simple and the instructions are fairly clear, actually putting it to use tells another story. The warmer requires you to refill a small graduated tube for each use, according to the chart provided in the instructions. Unfortunately, the chart can be difficult to understand and the tube is difficult to use. For example, the chart may require you to fill to the '4' line twice, which is NOT the same as filling it to the '8' line. And because the fill lines on the tube are so close to each other, it may take several minutes at the sink to get it filled to just the right level. It's no fun to have to prep the warmer for every use, and even less fun to have spend as much time on the prep as you do waiting for the bottle to warm!
Furthermore, glass bottles can not be used in the Orb which is very limiting. And, popular bottles like Best Value Tommee Tippee Feeding and Top Pick Comotomo are too wide to fit inside the warming chamber.
Born Free Tru-Temp with a 4 of 10. At recommended settings, it took 3:40 to warm a plastic bottle to 107F. Unfortunately, this is just a tad too warm for our liking and if left inside for a few minutes, temperatures will reach too hot. Boon recommends a wait time of about 10 minutes between uses to allow the heating element to cool down, which is fairly common (though inconvenient) for bottle warmers that use steam heat technology.
Ease of Cleaning
Chicco NaturalFit Best Value with an 8 of 10. On a day-to-day basis it just needs to be wiped clean with a sponge. This is easy to do as the plastic basket comes right out to expose the hot plate which is set inside a wide and shallow warming chamber. Mineral deposits need to be removed once a month by soaking the warmer chamber with for 2 hours with 2 ounces of straight white vinegar. The accessory parts are cleaned separately by hand or in the dishwasher on the top-rack.
Modern and compact, this warmer's strength is in presentation and ease of cleaning. Otherwise, it is aptly named in function. This Orb reminds us of a meteor cascading into Earth's atmosphere, a little too fast and hot for our comfort.
The Orb underperforms at its price point; for a much better value at a similar cost, we recommend purchasing Best Value Chicco NaturalFit.
We recommend parents consider one of the better performing competitors rather than buying the Boon Orb.
