I just got it, and my MacBook Pro fits in so well after adding an extra ventilation. I also use an iPad a lot so I looked at the images where they stacked an iPad Pro but its wonky even after putting in three extra ventilations. Its straight but its not fitted in nicely.
I think it would be great to buy or provide ways to create new ventilations at home or sell them to customers. I might be a minority user but I would love a few more ventilations strips so that I can use per case based.
Apart from that this is a wonderful docking station with an amazing bottom padding which sticks to the table. I really hope its a long lasting padding but I cannot recommend this product enough to people who love a docking station for home :)
