Penstar Penstar eNote Pro – The Clearest Color E-Ink Paper Review

The best color e-ink tablet for Android tinkerers. A great screen bundled with a good stylus, but let down by so-so software and a premium price. Buy it for the color, not the AI buzzwords.

The Penstar eNote Pro is a solid color e-ink tablet that nails the basics but gets a bit lost in its own feature list. The one thing you need to know is that it's a great Android e-reader and note-taker with a surprisingly good color screen, but you shouldn't buy it expecting a full tablet replacement. It's for writing, reading, and sketching, period. If you're coming from a black-and-white e-ink device, the Kaleido 3 display feels like a genuine upgrade, but our database shows it's still firmly in the 'specialist tool' category, not an iPad killer.

The screen is the star here. Scoring in the 80th percentile, the 10.3-inch Kaleido 3 panel is genuinely impressive for an e-ink device. Colors pop more than we expected, and the paper-like texture with the included stylus feels great. Where things get a bit wobbly is in the overall responsiveness. While the CPU and GPU scores are decent for this niche, the 38th percentile RAM ranking shows up in occasional sluggishness when switching between apps or loading complex PDFs. It's fast enough for its core job, but don't expect buttery smooth Android navigation.

Worth it? Only if color e-ink is your non-negotiable must-have. At its $499 starting price, it's a fair deal for the bundle you get. But the price spread in our data is insane—some vendors list it for over $95,000, which is obviously a glitch, but it tells you to shop carefully. Stick to Amazon or the official store. For pure black-and-white note-taking, you can get a reMarkable or Boox device for less. You're paying a premium here for color.

This sits in a weird spot. Compared to the reMarkable 3, the Penstar wins on color and Android flexibility but loses on that magical paper-like writing feel and ecosystem polish. Next to an Onyx Boox Tab Ultra C, it's a tougher fight. The Boox often has better performance and more refined software, but it usually costs more. Then there's the elephant in the room: a base iPad. For the same money, you get a blazing-fast, gorgeous screen that's terrible for your eyes and a writing experience that feels like plastic on glass. The Penstar is only the right choice if you've already ruled out a standard tablet for eye strain reasons and you really need color.

If you're looking for a general-purpose tablet to watch videos, browse the web, and play games, this isn't it. The e-ink screen is too slow for that. Go get a Samsung Galaxy Tab S9 FE instead. Also, if you want the absolute best writing feel on digital paper, the monochrome reMarkable 3 is still the king. Skip the Penstar if pure writing texture is your top priority.

We're giving this a cautious recommendation for a very specific person. If you're an e-ink enthusiast who has been waiting for color to become usable, and you want the freedom of Android, the Penstar eNote Pro is a compelling option. The hardware is good, and the screen is great. But if you're new to e-ink or just want a digital notebook, the software quirks and premium price make it harder to justify. Try a black-and-white device first, or spend more for a more polished color competitor like Boox.
