The Good The new Kindle Oasis maintains its slim design while adding a sturdier aluminum back and a larger 7-inch, high-resolution E Ink screen. It's fully waterproof (can be submerged) and can play your Audible audiobooks to Bluetooth headphones or speakers. Integrated light is brighter at its highest setting.

The Bad Expensive; no case included.

The Bottom Line While not as lightweight as the original Kindle Oasis, the larger screen, more durable aluminum chassis and full waterproofing are important upgrades that put the new Oasis at the top of the e-reader class.

When Amazon released its original Kindle Oasis e-reader in 2016, I was pretty impressed. It was really thin and lightweight and featured a top-of-the-line E Ink screen. It also came with a slick, removable leather cover that had a built-in battery. The only downside? It cost a whopping $290 or £270 in the UK or AU$449 in Australia.

Enter the "all-new" Kindle Oasis, 2017 edition. The first fully waterproof Kindle, it features a larger 7-inch E Ink display, a very slim design and an aluminum back. It also marks the return of Audible audiobook support to the Kindle platform. And technically it costs less, starting at $250 for the model with 8GB of storage. The Oasis goes up to $350 for a 32GB model with cellular connectivity, which has all-you-can-eat data plan included in the price for content downloads during the lifetime of the device. (Note that's only for e-books; you'll still need to download audiobooks on Wi-Fi.)

The big caveat is that the new Kindle Oasis doesn't come with a case, it's an optional accessory, starting at $45. So for those of us who like to use a case (I do) the price is essentially a wash. However, despite that, the good news is you're getting more e-reader for your money. By that I mean the larger screen is appealing, the aluminum casing seems to be more durable and if you use your e-reader in the bathtub, by the pool (or maybe in the pool) or at the beach, the waterproofing is a big plus.

Editors' note (March 14, 2018): Since this review was originally published, Amazon has released an updated version of the Kindle Paperwhite, which sells for $100 to $130 and includes many of the of Oasis's best features.

Bigger screen and battery

When you first see the new Oasis, the thing that jumps out at you is that larger 7-inch, 300 pixel-per-inch (ppi) display. Amazon says it's the largest Kindle display with that level of resolution. Compared to the 6-inch display of the original Oasis, which was also 300 ppi resolution, it provides slightly more than 30 percent extra screen real estate. That's a significant difference. Unlike the widescreen Fire tablets, the Kindles utilize a more squarish 4x3 aspect ratio, which is also nice.

The other big change is the battery. The original Oasis had a small battery built into the device and a larger one built into the included case, which attached to the e-reader magnetically. With the new Kindle Oasis, the larger battery is integrated into the device itself and as noted, Amazon has made the case an optional accessory. It also adheres magnetically but isn't a charging case.

The new Oasis tapers down to 3.4mm at its thinnest point and weighs in at 194 grams (6.8 ounces) -- 10 grams lighter than the Paperwhite, which has a 6-inch display. Amazon says the display's cover glass is the strongest to date, and the new dual-core 1GHz processor (with 512MB of RAM) is the zippiest too, giving you slightly faster page turns. You can either turn pages using the physical page turn buttons -- you can hold the device in your left or right hand -- or tap the screen.

The device being well balanced, I found it comfortable to hold, and the touchscreen is quite responsive. The text on the screen was sharp and had excellent contrast. My only small gripe is that the aluminum border has a slight edge to it. The edge does allow you to hold onto the e-reader more securely and perhaps doubles as an exfoliating tool (I jest), but the metal has a little less inviting feel to it than the plastic chassis of the original Oasis.
