Hello, nice to meet you! I’m new and wasn’t sure whete whether I should post this in the Digital Art forum or the Computer and Technology one so sorry if this is wrong.

I need to ask a question for experienced users. I currently own four pen tablets: A Genius 8×6 Mousepen I’ve had for ten years (?) now, after having a 4×5 one for 10 more years ; a Huion H610 (not Pro) I acquired around 2013 because my Genius pen had broken and I couldn’t find a cheap pen + wanted to upgrade ; a Wacom One CTL480 I bought again because the pen for my Huion broke and an upgrade seemed less expensive ; and a Intuos 2013 CTL472 I bought as used goods recently because it was really cheap and I’ve kind of always wanted an Intuos or some other .
Since then I managed to get a new pen for my Genius (by buying an old used cheaper model), for my Huion (those are easy to get o Anliexpress but I had to wait months for it so I bought the Wacom One), and now I have 4 working “basic level” tablets ; I’m very much an amateur user, I don’t really think of myself as a (drawing) “artist” and I certainly don’t need all of these, but I never know when one is going to break so I’m keeping them all for the sake of it. So I did some testing and even could upload it on Youtube in case anyone wants to see.
I don’t think any of these tablets are compatible so I wanted to know if anyone here uses 2 drawing tablets, any brand, and if so how did you do it. Thanks a lot!
