The individually adjustable support arms can accommodate the use of tablets ranging in height from 222 to 334 mm and width from 128 to 23 mm (for example iPad, iPad Air, iPad Pro, Amazon Fire HDX 8.9, Samsung Galaxy Tab from 9.7, Google Nexus 9, Asus Transformer or Microsoft Surface as well as Surface Pro). The depth of the tablets can vary between 6 and 11 mm. For the first use of the tablet holder the support arms settings are made by adjusting the clamp screws to the size and depth of the tablet. For other uses the tablet can be attached and detached quickly and simply through a snap lock. This provides maximum flexibility and mobility. A handy wing nut allows one to adjust the angle, so that each user will easily be able to find their ideal individual position. The tablet can switch between portrait and landscape positions. The tablet is kept in place, there is no danger of the tablet switching position by itself. - the manufacturer
