I've used a variety of china chargers, and am currently using this one with my nexus5. I've had no problems knock on wood The one you've linked sells for approximately $20-30 locally at shops here, and I've several friends using it with no problem.

I was originally using the new version Nexus Wireless charger and it wasn't powerful enough to make it through my Spigen Slim Armor case (which is quite bulky). I switched to this one, without magnets, but it gives a decent charge and with screen off, and wifi on (stock rom), battery monitor shows ~750mA (against flow) which is IMO is almost as good as a high amperage wired charger.

My Gnex has a horrible time keeping the cable in, so what I ended up doing was getting this receiver and this charging pad and just wireless charge the phone, and leave the receiver plugged in full-time and have a case on the phone. Personally, it's worked out pretty well for me, and any data transfers I have to do, I just use WiFi File Explorer Pro to transfer files. I'll probably go the charge port replacement route when I upgrade phones, but for now this bandaid seems to work fairly well.

I know the replacement is the cheaper option out out of this, but just thought I'd throw in my experience

I just bought a wireless charger for my Smartphone from Amazon http://www.amazon.com/dp/B00J2TEL28 that is working absolutely fine from last 7 months. It cost just around $15.
