Coming from Wacom tablets for the past 20 years, a devoted and unwavering fan, I finally decided to try out the competition.
I got the Deco Pro WM with Bluetooth, which is not yet available in Greece. So, I will only say that the Bluetooth works perfectly and I will continue with the evaluation of the rest.
The feeling of drawing on the surface is incredibly similar to using a pencil on paper (truly amazing). The stylus has a very good grip, the weight is just right, and the balance is exceptional.
It has pressure sensitivity in the stylus, which sometimes has some unexpected jumps, but nothing major, Wacom tablets also have that. It also has tilt sensitivity, which is supported. In Photoshop, it is supported with great results.
The quality of the materials is very good, with a metallic base (resembling MacBook) and a plastic surface on top. The buttons could be slightly better, but no complaints with them.
The scroll wheel is stepless and has a very nice feel. In the center, the black surface is a regular trackpad like those on laptops and it functions as a mouse or a secondary touch scroll wheel, depending on the setting you choose. The 8 buttons are very convenient for shortcuts with macros or button combinations. The shortcuts and the scroll wheel can be individually customized for each program. For example, in the Windows environment, the trackpad functions as a mouse, and in Photoshop, it functions as zoom. It works with Android, and the cable for connection is included.
The package includes a glove that glides on the surface for prolonged use. It also includes a case for the stylus and several spare tips, if I remember correctly, 8. By registering the product on the official website, you also receive a free application out of 4 options, essentially 2 because the other two are 3-month trials. Personally, I chose ArtRage 6 for painting.

Overall, it is the definition of value for money at this price, and I highly recommend it even for budget professional use, which is what I do.

After so many positives, there is also one NEGATIVE for which I was ready to deduct a star, but... The negative is that you cannot use 2 buttons simultaneously or a combination of a button and the scroll wheel. For example, in Lightroom, I have assigned one button to alt and the scroll wheel to brush size, but pressing the button (alt) and turning the scroll wheel does not change the size of the negative brush.

UPDATE
As of today, when I am writing this on 4/3/2023, it is still functioning flawlessly. The surface has some signs of use from the stylus, but it holds up well. With the new 2023 driver update, combinations of keys (shortcuts) now work, but not the combination of the scroll wheel and a button.

The XP-Pen DecoPro Medium replaced a Wacom.

Comparatively much more affordable (especially on black friday), excellent build quality, very fast response and amazingly fast response from the manufacturing company.

The stylus is used for:
1) Online lessons
The size, if you have space, is ideal, as the medium is almost A4 size and literally "solves" your hands. Plenty of space to write special types and draw charts.
The programmable 8 buttons with the round touch pad and the rotary ring will serve you very well!

2) Drawing
XP-Pen provides either OpenCanvas or ArtRage for free with the purchase.
Personally, I chose ArtRage and I am very satisfied with the hobby use I make of it.

The stylus is extremely lightweight and very convenient to hold. It also comes with 8 spare nibs and a glove.

It is also accompanied by adapters for connection to USB, micro USB, and C-type ports.

Visually, the blue lighting on the silver ring and the illuminated ends of the active surface of the stylus are very beautiful (adjustable)
