My Lumia 920 works anywhere on the charging pad but this required it to be in the exact sweet spot of the Qi coil

Have to find the sweet spot on QI charger, but it work great as an after thought for the price.

My guess is that the "sweet-spot" will not line up correctly

Might have to find the right spot on the charger to get it come

Initially I had to find the "sweet spot" on the charging pad - moved the phone around a lot until I figured it out

I've used it with TYLT QI chargers (love their 3 coil chargers!) and the Snowkids Wireless Charger on here (great cheap single coil, but you have to position it to the sweet spot) Works through Otterbox with all the above equipment.

At first I didn't think it was working because the metal pressure pads were not touching, but when I retried it with the back and my Pelican case on it, I realized I hadn't found the sweet spot on the charging pad!This device works great, but you just have to find the right spot with whatever charge pad you are using.

It does take a bit of moving on the wireless charger to find that "sweet spot" to get it charging, other than that i do reccomend this as a good option for wireless charging your S5.

I expected a lot of dead spots or contact problems, but this product works flawlessly every time (once you find the right angle/orientation to charge it in, which is very easy).I recommend this to everyone who has a "Qi enabled" smartphone now, especially since it can prolong the life of your phone since the charging port is usually one of the first things to cease working.
