Plastic and Metal Water Bottles

Published August 2015

How we tested

The alley behind the test kitchen isn’t exactly a bucolic place to spend a breezy afternoon, but I, along with a photographer and videographer, had important work to do: dropping refillable water bottles onto the pavement, over and over again, to test their durability. Call it a cold, hard real-world test.

We were evaluating eight different water bottles. There are thousands for sale, so we narrowed our lineup to stick with a few key parameters.

First, we focused on basic single-walled bottles and considered only BPA-free models. (BPA stands for bisphenol A, an industrial chemical used in some plastics. It’s currently under review by the FDA, but critics claim that it can leach into food and cause health problems.) Also, we nixed straws because they’re difficult to clean thoroughly and tend to get funky fast. We avoided bottles made from glass, too, because it’s heavy and, of course, breakable. And we were strict on price; anything north of twenty bucks was out. Our final lineup of eight bottles, each costing between about $10 and $20, was made up of five plastic bottles, two stainless-steel ones, and a soft plastic pouch.

We wanted a bottle that was easy to fill, open, close, carry, clean, and sip from. It also had to be spill-proof and exceptionally durable. Before each bottle plummeted toward the pavement, a succession of testers evaluated its basic functionality. We then filled them with an electric-yellow sports drink and let them sit for 24 hours to check for unwanted staining. Some were dishwasher-safe, while others weren’t; we hand-washed or ran each through the machine 10 times, depending on manufacturer instructions, to check for wear and tear.

We bought extras of each bottle and assigned them to staffers, with the stipulation that they use them every day for two weeks and take them wherever they go. The bottles went to work in the test kitchen and at local restaurants; they went on long walks around the city, hiking in the mountains, to the gym, and to yoga; they rode in cars, trains, and buses and sat on the couch through Netflix marathons; one even took a weekend trip to Cape Cod.

Meanwhile, we ventured into the alley with our eight testing copies. We shook each full bottle vigorously upside down for 10 seconds and then dropped each from shoulder height onto the hard pavement—upside down, right side up, and sideways. Only half the bottles survived.

Of the three materials the bottles were made from, the soft plastic pouch was too squishy and awkward for everyday use. The stainless-steel canisters were problematic, too; testers sometimes spilled while filling them because they couldn’t see inside, and they dented easily. Our favorite canisters were made of Tritan, a clear, hard plastic. We could see through them for easy filling, and they aced the dropping tests, bouncing off the pavement with nary a scratch.

Testers liked protected mouthpieces, which felt clean on the lips; exposed ones got dirty or dusty. And testers didn’t like complex bottles with fussy buttons or finicky, hard-to-undo latches. These complicated bottles were also less durable: More external doodads meant more to break off.

As far as being spill-proof and durable, nothing beat the classic screw-on lid. But some bottles were too wide to drink from easily, while others were so narrow that they were hard to fill and clean. Two bottles with screw-on lids tackled this catch-22 by mounting a second, smaller twist-off cap on top of the lid. One bonked us in the face while we sipped—less than ideal. But the final bottle nailed it.

Our favorite was clear. It was made of strong, clear BPA-free Tritan and had a smaller twist-on cap that opened and closed smoothly and was easy to drink from; its large opening was great for filling and made cleaning a cinch. It smacked down onto the pavement again and again without spilling a drop and looked nearly brand-new afterward. It comes in 24- and 32-ounce sizes; the former fit easily in larger cup, bike, and backpack holders. Whether you’re hiking, lounging, or squished on a bus, our winner is the best water bottle for staying hydrated on the go.

The Results


Design Trifecta 360 Knife Block

Admittedly expensive, this handsome block certainly seemed to live up to its billing as “the last knife block you ever have to buy.” The heaviest model in our testing, this block was ultrastable, and its durable bamboo exterior was a breeze to clean. Well-placed medium-strength magnets made it easy to attach all our knives, and a rotating base gave us quick access to them. One tiny quibble: The blade of our 12-inch slicing knife stuck out a little.


Schmidt Brothers Downtown Block

This roomy block completely sheathed our entire winning knife set using just one of its two sides—and quite securely, thanks to long, medium-strength magnet bars. Heavy, with a grippy base, this block was very stable. An acrylic guard made this model extra-safe but also made it a little trickier to insert knives and to clean; the wood block itself showed some minor cosmetic scratching during use.


Schmidt Brothers Midtown Block

This smaller version of the Downtown Block secured all our knives nicely, though the blade of the slicing knife stuck out a bit. With a base lined with grippy material, this block was very stable. An acrylic guard afforded extra protection against contact with blades but made it a little harder to insert knives and to clean; the wood itself got a little scratched during use.

Recommended with Reservations

Swissmar Bamboo Magnetic Knife Block

This small, scratch-resistant model had a stable, rubber-lined base and could hold all our knives, though the blade of the 12-inch slicing knife stuck out a bit. But inch-long gaps between its small magnets made coverage uneven and forced us to find the magnetic hot spots in order to secure the knives. Its acrylic guard made it safer to use but harder to insert knives and to clean.

Not Recommended

Messermeister Walnut Magnet Block

This handsome block was done in by its shape—a tippy, top-heavy quarter-circle that wasn’t tall or broad enough to keep the blades of three knives from poking out. It lacked a nonslip base, and its extra-strong magnets made it unnerving to attach or remove our heavy cleaver. Finally, it got a bit scratched after extensive use.


Epicurean Standing Knife Rack 12"

This magnetic block sheathed all our knives completely, though with a bit of crowding. But it was hard to insert each knife without hitting the block’s decorative slats on way down, and because the block was light and narrow, it wobbled when bumped. Worse, we couldn’t take it apart, so splatters that hit the interior were there to stay. Additionally, the outside stained easily, and when we wiped it down, the unit smelled like wet dog.


Kapoosh Rondelle Knife Block

This model stabilized knives with a mass of stiff, spaghetti-like bristles that shed and nicked easily after extensive use, covering our knives with plastic debris. While all our knives fit securely, several of the blades stuck out, making this unit feel less safe overall. Finally, though the bristles could be removed and cleaned in the dishwasher, their nooks and crannies made this block hard to wash by hand.


Kuhn Rikon Vision Knife Block, Clear

This plastic block required us to aim each knife into the folds of an accordion-pleated insert that was removable for easy cleaning but got nicked easily with repeated use. Because we could only insert the knives vertically, longer knife blades stuck out; a cleaver was too wide to fit. The lightest model in our lineup, this block was dangerously top-heavy when loaded with knives.
