very good ... but useful:

the part is actually just fine.
fits 7-10 inch tablets. So playbook with my Blackberry and Toshiba Excite AT10-A105.
By 2 fixable joints enough opportunity to align the part.
Very convenient the fold out holder is at the bottom when the tablet is clamped edgewise.
Attention:
With the pushbutton released and the ratchet teeth MUST to deal gently and carefully.
When the first support me broke after few days teeth out of the holders, because what had jammed.
Then came without problems spare Amazon :-)
When laid eyes on the disk should you breathe on the sucker a little damp ... otherwise tends the fall!
