Just had an email from Anker informing me of their latest special offer on Amazon.
This keyboard case is usually £35.99, but they currently have an offer limited to the 1st 150 people for £10 off using a code.
Synthetic leather exterior resembles a notebook and contains a comfortable, fast-typing keyboard to fully complement your iPad Air.
Versatile viewing options: iPad Air snaps to a magnetic upright angle designed for typing and media playback or lies flat over the keys for handheld use.
Opening and closing the cover triggers sleep or wake modes. Locking your iPad Air into the upright position automatically wakes the keyboard (once paired via Bluetooth).
Power-saving mode triggered after 10 minutes of inactivity. Category-high battery life of over 6 months between charges (based on 2 hours of use per day).
Package contents: Anker® Bluetooth Keyboard Case for iPad Air, USB charging cable, welcome guide. 18-month warranty, and free lifetime technical support.
