The IPS display produced realistic colors with decent viewing angles. It’s matte meaning that you should be able to view content on it outdoors, although it is not particularly bright. A full HD resolution on a 13.3-inch display is our preferred combination, resulting in a higher than average pixel density, which translates into sharper pictures and text.
The keyboard exhibits some flex, which shouldn’t be of concern unless you tend to type forcefully. Keys are reasonably spaced and have a good feedback/balance without being too harsh or spongy. It’s good to see full size Shift keys, but it’s a shame that there is no ‘print screen’ button.
The touchpad is responsive as well, with maybe a bit too much difference between the palm rest level and its surface for our liking. Clicking on the right or left button does produce a noticeable sound, which is what we’d expect (and want). Jumper also bundles a free piece of software called Touchpad-blocker which blocks accidental clicks while typing on the keyboard.
As expected, you won’t be wowed by the sound coming out of the speakers or the quality of the full HD webcam; the latter protrudes from the top of the display bezel, which is something of an oddity.

Sisoft Sandra (KPT): 2.15
Windows Experience Index: Did not run
UserBenchmark (higher is better): 46
Performance
The Celeron CPU helps the EZBook 3 Pro best any competing Atom-based devices with ease when it comes to sheer compute power. On the downside, the storage subsystem is another story altogether – seldom have we seen something as slow as this. You can, however, replace it thanks to a free M.2 slot (although sadly this isn’t easily accessible like on the Onda Xiaoma 31). Still, clearly this is a major Achilles’ heel for this otherwise very capable laptop.
As for battery life, we managed a reasonable 5 hours 9 minutes on our standard YouTube count-up video test at 100% brightness on default power saving settings (but with sleep modes disabled).
Final verdict
The Jumper EZBook 3 Pro already faces some stiff competition but remains one of our favorites alongside Chuwi’s LapBook 12.3 and the Onda Xiaoma 31, especially as it is, at the time of writing, the cheapest model to sport the standard 6GB/64GB combo.
It delivers a punchy performance especially in this price range with the added benefit of a superb design. We loved the keyboard (but yearn for the missing keys), applaud Jumper for offering some upgradability options and can only give a big thumbs up for the design and keen pricing here.
