1. The dongle that you have to leave plugged into your phone will not fit if you have a phone case (which most people do). You have to remove your phone case entirely for the dongle to fit properly. Really inconvenient. 2. The magnet that the ads show as being super strong is laughably weak. The slightest movement will disconnect it and if it's not on there perfectly the charger won't work at all. 3. When the magnet does stick the charge is inconsistent. Sometimes it works, sometimes it doesn't. 4. One of the USB plastic covers broke immediately after I got it out of the bag. 4. The customer service that they brag about on the website is nonexistant. I have been trying to get a refund for a month now and no one will return my emails. And that's the only way you can get a refund. If it walks like a scam and quacks like a scam...
