I have an x5c-1 and was thinking of trying a key chain cam to save some weight. Worth it or not worth it ? If yes, recommendations please. Thanks.
If you need a lightweight solution they are your best bet. http://www.Banggood.com/808-NO_16-HD-120-Degree-Mini-Camera-Module-7g-p-82197.html
FWIW don't go shopping for best prices on eBay, many shoddy copies. This is a legit vendor (and always recommended), here you can one with a full cable assortment. http://www.ebay.com/itm/Mini-DVR-808-16-V3-Lens-D-Car-Key-Chain-Micro-Camera-HD-720P-Pocket-Camcorder-/180937263580?hash=item2a20b389dc:g:aaoAAOxycmBS01Wl
