Honestly, this is pretty nice!
Color: Black, Color: Black
At first I was a little disappointed in the design of this device because the mat and the charger are two separate pieces; but the magnet that is connecting them together is pretty strong, so I ended up not minding it. The magnet in the charger is pretty strong too, though, so the whole thing tends to lift up when you pick up your phone - this is my first MagSafe charger, so perhaps that is standard with these, I wouldn't know.
As you can see in the picture, this isn't your standard mouse pad. It's leather on one side and felt on the other (you can pick which side you want to face up, which is a nice design feature, I suppose). It's smooth and wipes off easily but really collects fingerprints and hairs.
It's also a good size. Not too big, not too small. I was a little worried because it's smaller than my older mousepad but I haven't suffered for it. I may even prefer this smaller size if I'm being honest.
I'm not sure if I like the feeling of the leather side against my arm/wrist, though. The mouse has no problem reading it but it's just not very soft. I do notoriously dislike change though so maybe that's just a me problem LOL.
All in all I'm happy with this and would suggest it!

Worth every penny!
Love this desk mat!
Huge, sleek light-gray mat with built-in wireless charging. Fits my full keyboard, mouse, and phone perfectly. Super smooth for the mouse, stays put, and instantly made my desk look way cleaner. Great quality and worth every penny!

Still Usefil for a Samsung S24 Ultra User
Color: Black
The Charging Pad:
The pad is super flat (nearly the same thickness as the pad) and looks nice next to it or a similar mouse and keyboard pad. It works perfectly for my Samsung S24 Ultra without a case on it, but having a 'magsafe' style case would improve the experience. You do have to take a second to get the alignment right.
It uses USB-C instead of cheaping out with a micro, and the status light is helpful. I don't think I own anything that can charge in the headphone area, and in case you're wondering, neither spot will charge a Samsung smartwatch (as expected). I'd nearly recommend this just for the charging pad since it's so unobtrusive on the desk. Just remember you'll need to route that wire out of the top of it somewhere.
The mouse pad:
The size is probably perfect for a typical keyboard and mouse user. I always have a 3D mouse on the left, and an extra long Coursair keyboard, so I prefer having a gigantic mat for all of that. But there is one feature of this mouse pad that I like more than most. The material doesn't attract every spec of dirt and hair in the universe, and it's easy to wipe off. Because of this, I use the pad under my 3D mouse and keyboard, with a larger full-desk pad underneath (including the mouse area).
The felt material on the back keeps this locked to my desk, and unlike a rubberized pad, isn't going to turn into glue after a few years.
I did test my mouse on the pad, and it feels fairly good. It's not too smooth, and is a bit easier on your hand, but very serious gamers may take some time to adjust.
