I bought a Huion GT-191 (it's a pen display tablet) years ago and I used it for 3 years and never had a problem.
I then sold it and bought the next model (GT-220) and I have used it for a year or so, and again i am super happy with the product!
The GT-191 was not an IPS display, so the colours were off (even more so if tilted), but overall I still recommend it for beginners (it's cheaper and I used to fix the colours on the main screen).
I also made a video showing the main differences between the two: https://www.youtube.com/watch?v=ImeMAgCCGDM
