Bests & Worsts Reviews from Amazon

This is a decent keyboard in regards to actual typing, the price is right, and so far the battery seems to do pretty well. However, there are two major flies in the ointment that keep me from giving it a good rating. First, while the first bluetooth hookup is painless, from then on you have to remember to hit "Function" and "Z" simultaneously to re-pair, at which time it forgets the old pairing. I find this a considerable pain because I use this keyboard across multiple devices. Additionally, once the instructions were gone it was virtually impossible to find this resetting information on-line; it took me several hours. But even worse, the thing goes to sleep in mere seconds when left idle. I'm an author, and write exceedingly long documents with frequent multi-minute stops to consult references and, sometimes, just think. It doesn't aid my concentration at all to have my iPad soft-keyboard appear suddenly on the screen, interrupting my train of thought by reminding me of what a poorly-programmed keyboard I bought. This is obviously meant as a battery-conserving measure, but it's a grossly misguided one. I'm using this keyboard for now, but even though it's the best-typing inexpensive bluetooth keyboard I've ever come across-- and I've tried several-- I plan to keep looking for a replacement becasue it's also the only one that continually interrupts me when I'm trying to work. (Students attempting to write reports will very likely encounter similar problems.) I don't care about battery life nearly as I much care about being constantly interrupted by too short a sleep-time. Not everyone types only brief notes. EDIT-- 3 Sept 2015-- Anker contacted me as a result of this review and explained that the keyboard isn't supposed to go to sleep so quickly; rather, it's supposed to remain awake when idle for up to 30 minutes. Mine, they claim, was defective. They refunded my money despite the fact that I no longer had the box. Their customer service was excellent and they deserve recognition for it. So I've upped what was a three-star rating to four.
