I purchased a Cube Iwork 5X last September and I am still satisfied and have no major issues. The few minor issues could probably be fixed with firmware/driver updates so I occasionally look on the web to see if anything is happening. It seems the Iwork 5x has dropped off the map. It’s not listed on the Alldocube website nor is it “in stock” at Gerabest of Aliexpress. I ask Cube if any of their stylus ‘s are usable on the Iwork 5x (mostly to gauge their support). The answer is “no”.
I suppose if there are never any updates, I still think it is a fair deal at the price with featured I wanted .. can’t complain. I’m curious however about why the product life was so short.
