YOU SHOULD KNOW BEFORE BUYING
i7 Stylus is a 10” Windows 10 tablet that I just bought for
portable light sketching and painting purpose. It’s affordable with
the price tag of $300. There are many things I like about this product
while it has MANY, MAJOR FLAWS. Here I
will report everything I discovered so far.
- IPS type panel with wide view angle. Standard-gamut with horrible color space coverage of 67%
sRGB, 46% AdobeRGB. Cuts off around the far ends of green, blue, purple and red areas. Not so much for yellow and orange.
- Very bright backlight. 400cd/m^2 at max. No flicker at low brightness level. 120 cd/m^2 is at about 30%.
- White point 6600K, decent but still cooler than ideal.
- Tone Response Curves look very good. Almost dead straight.
- Average deltaE is merely 0.17. This is kinda amazing, it explains the straight TRC performance described above. Despite its small color space coverage, whatever it can display, it displays them super accurately. You don’t really need to calibrate it. As a result, it produces not rich, but very clean color, leaving me the impression of Microsoft Surface Pro 4, even though the SP4s have nearly perfect screens. You might want to be careful not to use extremely saturated color when drawing, because it cannot reflect those.
- It’s glossy, super reflective!
2) PEN & TOUCH
- Wacom Penabled display. The same technology of the old Cintiq line. Compatible with a zoo of weird pens!
- Original stylus has 1 side switch. I use my Cintiq 18SX’s 2 switch stylus (THE BEST OF ALL. Model: UP911E-02DD, available on Amazon.).
- Original stylus has 1024 level pressure sensitivity. My trusty 18SX stylus has 512, but you won’t tell the differences. They both worked well enough.
- The display surface is a bit slippery. Use Wacom felt pen nibs to increase friction.
- Fujitsu 10 point touchscreen. Works better after the removal of the included screen protector sheet (it has bubbles under it -_-). It doesn’t cooperate with Wacom’s stylus – no hard-wired palm rejection. Windows 10 can do this for you – search in Cortana for “Pen Settings”, check “Ignore touch input when I’m using my pen”. To turn it off completely, in Device Manager, disable “HID-compliant touch screen”.
wise, under Ubuntu 16.04.1, 1 of 2 side switches of my 18SX stylus
would not function. No dice with xsetwacom and xinput. When stylus
and touch both activated at the same time system locks up for a
while. I’ve reported this to linuxwacom project.
3) SPEED & STORAGE
- It call itself i7, but it’s a dirty trick. It actually has Core m3-6Y30, 4GB RAM, HD Graphics 515. I feel no slowdown at all when drawing an A3 300dpi picture in Krita.
64GB M.2 SSD. It reads like a rabbit and writes like a turtle. Boots
up system in a flash, but when Windows 10 is
undoingupdating itself, you can feel that writing queue is lining up straight to Uranus.
- Has a MicroSD card slot. Storage space is not an issue.
4) OTHER STUFF
- 3 hours + under stress running time, at 30% brightness level (120cd/m^2). Lasts forever when browsing webpages. Gets red hot when you are both charging
and running 3Dmarks9000 on it.
adapter not included
in the official package list. At least not in China where its
DC 12V 3.5x1.35mm jack. Good luck finding that! In China you must

I scavenged an adapter from a dead router and gave them 2/5.
I was writing this report, they phoned
me one for free anyway.)
- 1 USB Type-C connector. You may charge it through this connector, but your charger must have 5V2A standard USB power output to do that. QuickCharge(QC) devices and alike are not guaranteed to charge it unless their non-QC, conventional mode can output 2A. Also, it seems to charge only when you plug it in after the machine is booted into the system. If you connect its USB-C before turning it on, it might not boot. USB-C connect does not support startup disk.
- No documents, no tech support, no drivers on website Not even on the Chinese version. They are serious about national equality here. No. Quickstart Guide does not count as a legit piece of document. The Recovery ISO is hosted on a 3rd party, Chinese equivalent of dropbox as a dodgy .rar file like a p0rn video. Very unprofessional. If you are going to install Windows anew, you’ll need to find your own drivers. (Search for: Intel Driver Update Utility / Wacom Feel Driver / Realtek High Definition Audio Driver)
- The keyboard is detachable. In tablet mode it feels very light weight to be hold in one hand. Unlike Cintiq 13HD, this one I can use for a long time without having sore in my arms. The keyboard itself is very well made too. The whole frame is cut out from a piece of metal, probably steel. No squeaking sound. Super steady. Very heavy. Holds up the screen nicely. Definitely one of the best in this size.
major usability issues. Instead
of using software to handle the gestures, it seems to embed the
recognition in the hardware and send out keyboard signals when it
thinks your movement is a gesture. Very easy to misfire commands like minimize all windows, zoom, swipe and
task view. There is no way you can turn it off. Just don’t let your fingers go near its edge.
- The earphone jack packs a punch. The audio chip is the infamous Realtek ALC283. This crap has no right to drive my Etymotic ER4B loud (you monster!). But it did! At only 25% of the volume, too! Did they bother to put an amp chip in it? It sounds quite musical for a cheap tablet, too! I have to write about this. What a strange breed of product we got here. XD
- Has 2 cameras, each on both sides. The sensors are OV2680 and OV5648, controlled by intel Imaging Signal Processor 2500. They are absolutely crap. You got nothing but noises. Probably not good enough to provide evidence of a crime scene. :P
- Audio jack and power adapter jack look exactly the same. I often plug the power adapter connector into the audio jack. Although it doesn’t bring any danger because of the structure, it still makes me like an idiot.
what a piece of crap! But at the end of the day, it’s better than
Just joking. Despite all those problems, I still love this product. It’s very well built and doesn’t feel cheap at all. Nothing top-notch but all good enough for my target purpose - portable sketching. At the price of $300, I consider my money well spent.
But still, I DO NOT RECOMMEND IT FOR NON-TECH ARTISTS. You must know how to deal with its atrocities. Otherwise, YOU GONNA HAVE A BAD TIME, KID.
