Amazon lists this spare part under Nexus 7, but it is for the 8 series. A slightly clearer indication would be helpful.

Absolutely identical to the original, very high quality (Made in Japan). Easy assembly, fits like a glove. Price (incl. free shipping) is very fair. I would recommend the product and seller without hesitation.
