Each Orion Stand is machined from 6061-T6 aluminum then anodized one of three colors, Black, Gun Metal Grey, or Limited Edition Kick-Starter Green. (The Limited Edition Green is reserved for those that support us on Kickstarter). Each stand has 6 rubber o-rings, which provide a soft surface for your iPad or tablet device and prevents the stand from sliding on surfaces. Each part includes 2 magnets which allows for quick assembly and disassembly of the stand. No need to worry about strength, each magnet has a 2.2lb pull force rating which totals 8.8lbs per side!
