5 stars leave no room for improvement, because there are definitely drawbacks. The Touch Ring for scrolling works for example not always. So sometimes I have to first with the pen on the tablet touch so I can scroll. Therefore, I give 4 stars. All in all, it is certainly not a professional device (is also much cheaper), but I said above, for Photoshop is a great relief.
To the already often-noted whistle I want to say the following. If I hold my head as close to the tablet that I hear the whistle, I can not work with the tablet because the head is in the way and I can not see the monitor. That is the normal work is not for me to perceive the whistle.
Conclusion
I think this device is designed for hobbyists a highly recommended investment. Especially vision is hereby substantially facilitated. Professionals have certain other requirements, I can not judge, first, and second, there is for professionals related hardware.
