Let's start by saying that I bought this pen because the product description says it is for the Galaxy Tab A 8 inch (I have the tablet and the one you see in the video). Even when fully charged, the pen tip is very slow and lags when drawing. I could handle that, no problem, but the alignment seems to be off by 2-3mm. That's quite a lot if you're expecting accurate blueprints. The back of the grip works as expected, but that's not what I bought this grip for. I bought it to use the tip of a pen for precision. Serious disappointment. Certainly not worth the price paid.
