thanks for the suggestion of the non-Samsung branded wireless charger.
the whole idea of having to concern myself with how warm an off-brand wireless charger would make my S5, etc, all worry me to some extent. these issues were written about by some of the reviews on that charger.
as unpleasant as it is to have to wait for the Samsung accessories to come out, i know i'd regret not waiting for them once they do become available. i even worry about an off brand foil-like accessory to the inside of the caseback. these have the possibility of screwing things up if designed poorly. with the original, Samsung-branded wireless caseback, we know the foil inductance receiving foil is permanently ON the caseback itself and that it is properly designed, thereby lending a level of peace of mind.
i'm impatiently waiting for the Samsung wireless charger to come out. it's ridiculous that they have this inconvenient microUSB3 port cover and yet get the phone out the door but the wireless charger with no "available date" whatsoever. their samsung.com website is also sorely lacking. poor feedback to customers. it doesn't say at all when it is expected. when i so-called "pre-ordered", it didn't even take a credit card!! all they did was to send me an email saying that they'll notify me when the charger becomes available and then i can place an order. well, that's not pre-order! that is pre-notification! yikes. poorly run website.
