Get for $15 Only a Qi Wireless Slim Charging Mat (Smartphones)

I never know that I can charge my smartphone wirelessly! My friend told me that it's a cool accessory to smartphones now. So, I did a quick research and there it is! Kogan is currently running a presale on Qi Wireless Slim Charging Mat for $15 only including delivery cost! It'll be shipped out from warehouse on March 31. It is normally priced for $29 and last year's sale, it was for $19. So I guess, I save big on my first wireless charger. It says it's slim, lightweight and I just need to connect it with USB power source and place my smartphone on top of it to start charging. Overcharge battery protection is even built-in with this device! It looks quality and reliable to me so I will get one now for myself. By the way, it says Nexus 5's owner should have one of this charger.
