In a complete glove, the hand sweats, it is sewn from a terrible synthetic material (in Khayon, the material feels better).
At first, the unpleasant squeak of the tip on the tablet is annoying (compared to the Vac STL-460 (it also “shorted”, but not so loudly), but you gradually get used to this sound and stop noticing it.
The tablet is easily soiled - fingerprints are everywhere, rubbed off with difficulty.
Before buying, you need to check if you have a place for its comfortable placement, because the tablet is quite large.
Not everyone succeeds in replacing the tip of the stylus the first time using the device in the tube, but I had no problems with this (I tried to replace it just out of curiosity, the very first tip did not have time to grind off in a week).
In reviews on the network, they write that the quality of the tips from the kit does not match the quality of those sold in the store, supposedly the complete ones are very soft and wear down quickly. It's fair to say that I haven't noticed this yet, but a lot will depend on your technique, goals, and how often you use your tablet. So far, I have noticed that the leg at the tip may be a little thicker and then it will not work to fix it. It follows from this that marriage is found in consumables, which is not surprising and there is nothing wrong with this, in general, there is no.
Judging by the reviews on the Internet, sometimes, for unknown reasons, the driver settings fly off. I have such an incident happened 1 time after a sudden power outage. No more problems have been found with the software so far.
Sometimes, when working in wireless mode, the pen starts to slow down for 5-10 seconds (the cursor moves with a delay, but without jerking), this was not noticed on the USB.
Built-in non-replaceable battery. There are no comments here. I hope that under normal operating conditions, its service life will not cause any complaints.
No pen tilt sensitivity (but not claimed).
No warranty when buying on the well-known Chinese site. Representative offices in 2022, as I understand it, no. Only the official store and showroom.
