Review on 📱 TFY Security Hand-Strap for Tablet PC - iPad (New iPad/iPad Mini & Mini 2 & Mini 3 / iPad Air/iPad Air 2 / iPad Pro 9.7") - Samsung Tablet Pcs - Nexus 7 / Nexus 10 and More (Black): Ultimate Protection and Comfort for Your Tablet! by Eddie Duncan

NO finger-tightening device and this is no exception. Since such a band presses directly on the knuckles when using the hand, it is uncomfortable and hurts after a while. This applies to anything it does with its fingers. (Even a small handle on a plunger isn't ergonomic because it also requires flat fingers.) So I recommend looking for another type of fixture to hold the tray. If possible, use an adjustable arm holder that attaches to the table. you will thank me Otherwise, get a case with a bezel big enough to keep it off the edges.
