Functions well
Color: Black
This 3-in-1 wireless charging station works really well and makes charging everything in one spot super convenient. I love being able to charge my phone, watch, and AirPods all at the same time, and the setup looks clean and organized on my nightstand. The magnetic charging works great and charges devices quickly. The only downside is that the MagSafe attachment comes off pretty easily, so you have to be a little careful when placing or removing your phone. Overall, it’s a great charger that works well and looks nice, just wish the MagSafe connection was a bit more secure.

Updating my review, this is a very good product and I was wrong!
Color: White
OK, feeling like a bonehead. Originally unboxed and connected this device to my desktop power supply for a USB powersource. It did not have enough ampirage to charge my watch. I swaped that out before tossing, and found that the supplied power source worked just fine and the device charges both my phone and watch beautifully. So I'm a dope, the product is great, and I am here to correct the review! Given that said, my one gripe is that the adjustiblity of the mount is a bit limited. It's totally functional, but doesn't pivot 360 degrees, and does not telescope like I was expecting. Regardless, it is sleek, a huge space saver, and dejunkified my desktop a great deal. I would defintely buy another one of these. ORIGINAL REVIEW NOW RETRACTED: Annoying. Doesn’t operate as advertised. Watch charger totally inoperable. Mag charger does work. Very disappointing!
