How many people who are negative about the product have actually tried one at home?
I got mine today and I really like it. I expected it to be lighter (weight) than it actually proved to be. The phone attaches easily. It is easier to get the phone off the Duo, when you want the phone. In fact, way easier than with the MagSafe puck.
One of the things I really like about the Duo, is the compact power plug from Apple. I have had the Belkin and Mophie multi device chargers and there power adapters can be HUGE. Moreover, the fact that you are using one compact power source, rather than two, can be important if you live in an older dwelling where outlets and access to them can be severely limited. For me, that is why I purchased the Duo. Same can be said for office charging. Well spaced and easily accessible outlets are not always possible, when doing wireless charging
And about the price? People can spend well in excess of a $1000 for a phone and yet quibble about the Duo being $30 to $60 over-priced. I don’t get it.
And about charging speed? If you put your phone and watch on the charger and then go to sleep, is charging speed critical, as long as it is done by when you get up.
The negativity here can be significant.
