I've been using a remote control for a few months and others might find this useful as well.
The ckeyin (spelled c k e y i n) remote easily fits in the palm of the hand and is about the size of the Creative audio MP3 device and about the same shape. Most folks will likely never have seen the creative offering which died out about 10 years ago. Anyway, the Ckeyin remote is quite small and has real feel appeal. For purposes of clarity, I will define the top as being the end where the included key chain can be attached; the bottom includes the on/off switch and the USB charging port.
Starting then from the top, the ckeyin remote offers the following functions:
play/pause which is a semi-circular button, rounded side up.
Below is found a rectangular button, the right end volume up, the left end volume down.
Moving down again is the next/fast forward on the right end of the semi-circular button; backward/fast rewind on the left. The rounded side faces downward.
The final circular button is the photo button which works when the photo app is loaded.
On the bottom of the unit is the USB port on the left, the on/of switch is a pointy projection on the right. Moving it to the right is on, the left is off.
Links for the US and Canadian sites are as follows:
I did not find anything on Amazon for other countries and, checking the actual ckeyin web site, no mention is made of this remote control.
The price is about $12 Canadian and as I recall, about $4.00 US. (some things just ain't fair!)
It may take some practice to feel the buttons which are not raised from the rest of the surface. I suppose one could use lock dots to help out here. For me, using this remote is a lot safer than handling my IPhone on a cold day; I can work this device while inside my gloves. BTW, the included key chain is not reliable against a solid yank.
