I like the LG Quickcover, but it's far too pricey on the Play Store…however, I saw this on eBay.

Available in Black, White, Gold & Red.
On the Play Store though, the backing says LG, while this one says Nexus, so I'm not sure if this one really is genuine and has any differences besides the name on the back. The seller has over 99% positive feedback though…
Also, was looking at the Nexus Wireless Charger which is also very pricey. Is the Qi Wireless Charging Pad a good enough replacement?
You have to be careful with the wording on eBay listings. It doesn't say 'Genuine Google/LG Nexus 5 case', instead 'Genuine case… for Google Nexus 5'. The term genuine and original are used very sneakily on the internet, particularly from Chinese sellers :)
