Received the Inspire 1 Tablet Holder No. 45. The lower bracket is made out of Aluminum. Night and day for support for a large tablet. The box had a battery on it and I thought my second battery had come. Did not expect the holder to arrive so soon. In my excitement I thought the battery had arrived. The holder was $30 dollars and a way better replacement for the crummy plastic one that shipped with P3. Fits the P3 Tx perfectly. I guess if I spent $3000 for the Inspire I would have gotten it.
