Too slow
I got the Nexus 5 when it was released and pretty much every wireless charger to go with it.
These days I only use wireless charging when in the car on a short journey or when I plonk the phone on my desk wireless charger. Any time my battery is >70% full anyway, just to keep it topped up.
The problem is they are no competition to a good 2 Amp wired charger. Wireless takes twice as long to charge. If I actually need to charge it as it's running out or I am going on a long car journey, I always go for a wired charger.
