The Tether Tools Studio Proper Wallee Hand Strap is part of the Tether Tools Studio Proper Wallee modular system, and works together with your tablet in its Wallee case (both sold separately). It allows you to hold your iPad 1st, 2nd, 3rd or 4th generation with Smart Cover or Galaxy Tab 10.1. During a photo shoot, this strap can offer a very professional way to allow clients to preview your images. The handle is easy to use -- simply place your Wallee case over the locking X on the hand strap and rotate the iPad or Tab to secure it on the hand strap. Turn it and you'll hear a click. You can rotate the tablet between portrait and landscape mode by twisting it 90 degrees and it locks into place.
