** _Fit and Finish_**
The size and shape of this e-reader remind me of my old Kindle Oasis, except with a cheaper finish and without the battery bump. As a lefty, I appreciate that I can rotate the device so that the buttons are on the left side if I so choose. It is a bit of a novelty to have side-mounted buttons again; only my Pocketbook e-readers have buttons but they're on the bottom where orientation is less of a concern. The device has a nice textured feel all around with a leathery feel on the back. It's reasonably grippy and because it's not terribly heavy or thick, it isn't a pain to hold for extended reading sessions. The buttons are large enough to use by feel and have a decent clickiness to them. I don't necessarily need buttons, but it is nice sometimes to not have to sweep the screen to turn pages, especially on an e-ink device that isn't always as responsive as an LCD or OLED panel. The buttons control volume when you're not in an app that requires page turning. The screen is not at all flush with the bezel; it sits a few millimeters down. While this gives the appearance of a much older and less modern device, it does offer some protection for the screen. Placing it face down shouldn't be an issue. And the grippiness of the back means it won't slide around too much on most surfaces if you're using it flat on a desk or table. I have an Onyx Boox Nova Air C and a Pocketbook Verse - both 8" or smaller - and the feel and design of the Ocean doesn't really feel dramatically worse or of lesser quality than either of those. All three devices have relatively large bezels, and the Pocketbook also has a screen that is recessed from the bezel. If you're used to the feel of a Kobo or entry-level Kindle, you'll probably find that the design and feel of this device is comparable. It doesn't feel cheap, but it doesn't feel like a premium device, either.
**_Performance_**
The processor in this e-reader isn't super powerful, but it's enough to allow the device to respond reasonably quickly for most tasks I have attempted to perform on it. Large PDF files open and without much delay and I'm able to page through them without feeling like I'm waiting for the device to catch up. However, such a small screen isn't ideal for PDF viewing. EPUB files open and are navigable with hyperlinks performing as expected. On-screen gestures work surprisingly well when you're holding the tablet in your hands but are hard to pull off when it's lying flat on a table. You can swipe from the top right corner to open the panel for screenshot, study notes, or task switcher. You swipe down from the top to open the control panel, from the bottom left to open the task manager, from the bottom middle to go home, and from the bottom right to open the display optimization settings. These display settings aren't quite as robust as what Onyx Boox offers, with specific DPI and contrast settings by app, but you can alter black enhancement, set weak or strong anti-flicker, set how many pages are required before a refresh, and set refresh modes for clarity or speed. By default, the system display is set to refresh at the clearest setting, and the reader app is set to "Quick Brush". The settings themselves are a little odd: "The Clearest", "Quick", "Quick Brush", and "Intelligent". When scrolling web pages, the Clearest setting is indeed pretty clear and ghosting is cleaned up pretty quickly as you release your finger or pen from the screen. The Quick setting will result in more ghosting but less flashing. Choosing the Quick Brush setting will inform you that it will use more power. This setting is better for video than the Clearest or Quick settings, which will flash much more as they attempt to refresh and clear ghosting. Intelligent is also pretty decent for video, but Quick Brush is arguably the best setting for fast moving objects on the screen. The Clearest setting probably matches up best with what is frequently called "Regal" on other e-readers. The Quick Brush setting matches up with the quickest refresh settings on e-readers that provide the best viewing for video and animated graphics (e.g. Speed modes on Onyx Boox devices). As it's a black and white e-reader, the screen always looks sharp. You don't have the color layer making everything seem half as sharp.
In the month or so that I've had the e-reader, I have charged it twice. The first time was after I got it out of the box and the second time was after I came home from Christmas vacation. The e-reader was at about 30% after about three weeks of intermittent usage. The more time you spend reading, the better the battery life will be as quick refreshing of the screen will drain the battery faster. Battery life seems to me to be very good. I have to charge my Onyx Boox devices much more frequently, but they are color devices and perform better with a brighter lighting setting. I also tend to use them with apps more often, but I tend to read more on the Ocean because of the nice crisp lettering. I'm a fan of the screen on this e-reader; it's a nice look after so many years of Kaleido 3 e-ink screens that always seem ever so slightly fuzzy and washed out.
**_Pen Performance_**
The pen did not come with the e-reader, and I did not buy the Musnap branded pen. After playing around with a few different styli, I realized the e-reader supports USI stylus pens and I have a Penoval in my collection that I've used with my Pixel Tablet. As with most pen-enabled e-ink e-readers, using the pen for notetaking is best done with the built-in app. The pen and screen aren't optimized for third party apps. Some apps, like OneNote, will update your writing after you lift the pen so you aren't waiting to see your letters appear on the screen. The pen is fairly responsive in the built-in notes app, but my handwriting isn't that good. It looks much better with a Wacom EMR or AES stylus. It's fairly comparable to the experience I get from an N-Trig/MPP pen on a non-Microsoft device as I think Microsoft puts a bit more effort in optimizing MPP performance on their Surface devices. My handwriting on a Surface, especially the Surface Duo, always looked great. It looks somewhat messy on the Ocean, even when I am trying hard to be neat. I won't spend a lot of time here on the pen since I don't have the Musnap pen. Just know that a good USI 2.0 stylus will work and the experience will be comparable to a decent USI-enabled tablet (e.g., the Google Pixel Tablet).
There is a microphone and speaker on the Ocean but neither of them is particularly good. You can use the speaker for audiobooks or podcasts if the e-reader is very close to you and you can use the microphone to record voice memos if you hold it close to your mouth.

**_Reader App_**
You can take draw on or take notes on PDF or EPUB, but the tools aren't extensive. By default, you have access to a ball pen, but if your pen doesn't have an eraser (like the Penoval pen I'm using), you will have to use the handwriting menu to erase, which can be activated from the top menu bar (by tapping in the middle of the screen). The reader app keeps track of your notes and drawings, and you can easily see on which pages you have written notes of some kind. You can highlight or underline text. You can create bookmarks and search within the file. The device supports side-loading font files. I downloaded a few fonts from Google (fonts.google.com) and they worked just fine. You'll need to install a file manager that can unzip files to use font packages from the internet, but once you have that sorted, you just put them in the Fonts folder on the device, and they'll be available to use in the reader app.
As with Onyx Boox devices, you can access the e-reader over Wi-Fi and transfer books and files that way. It's speedy and easy but probably not even remotely secure. You can also transfer files via USB cable or install an app like Google Drive or OneDrive and download files from your cloud storage.
There is a switch in settings to turn on Google services, and once you do so, the Play Store appears, and you can install apps as you desire. Google apps like Play Books, Google, and News all work just fine. I installed several other apps and didn't experience any issues. The apps perform reasonably well, and I haven't had any crashes or system bugs to bog me down. I don't have any expectations that the device will ever receive any security patches or updated Android versions. Even the big brands are pretty terrible about updating the Android aspects of their firmware. My iFlytek AINote 2 has received several updates to firmware, but only to address bugs. Onyx does add useful features to their built-in apps over time but hasn't ever provided any Android version or security updates. If updates are important to you, buy a pen-enabled tablet from Samsung, Lenovo, OnePlus, or Apple or an e-ink device based on Linux like the Kindle Scribe, Remarkable 2, or Kobo Ellipsa.
The built-in apps on the Ocean aren't unique or especially capable, but it is a nice plus that you do have some apps. You won't get these features on your average Kindle or Kobo. The calculator, music player, audio recorder, and calendar apps are all very basic. There is no syncing to Google or Outlook calendars. The dictionary seems to be more of an English-to-Chinese translator than anything else, but you can add words from your books and save them to your "Vocabulary Book" for future reference and remembrance.
All in all, I don't think that this is the best device for notetaking. There are no syncing services and although there are some advanced features like layers and audio recording, there are better apps available on the Android platform and there are other devices that support Wacom EMR pers that will have better pen performance and a more of a pen on paper experience. The built-in e-reader is fairly basic, but it covers most of the bases if you just want to read and maybe occasionally highlight, underline, or scribble something on a page. But because the device runs Android and has the ability to use the Play Store, you can add other reading apps that provide whatever features you are seeking. And because OneNote does work fairly well, that's also an option if you want a more robust note-taking option. This device shines for reading with its crisp screen and the flexibility of Android means you have the opportunity to do more with it than just read EPUBs and PDFs. If that appeals to you, this may be worth your consideration. If you're serious about note-taking, you'll probably want to consider Onyx Boox, SuperNote, Remarkable, or AI-powered tablets like the iFlytek AINote 2 or Viwoods AI Paper. And if you're serious about reading but are tied to a particular ecosystem like Kindle or Kobo, you may want to consider the readers that run on those platforms. The Ocean is a nice little e-reader for reading books and using text-based apps with some occasional notetaking.
