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.

Smaller and more expensive than artisian deskmats
Color: Black
These are slightly smaller than the standard artisan deskmats and double the price.. It's also about half the thickness, so there's not as much padding. This isn't a huge deal. if the felt is on the bottom, it doesn't grip to the desk very well. The wireless charger is okay, but I found it bulky. Having a small dedicated 3 in 1 charging stand was more convenient for me. If you have a heaver mechanical keyboard, you won't be able to lift this thing to see underneath it. Overall, this is an okay deskmat and it'll serve it's purpose when I'm washing my regular deskmat, but not my favorite.

Don’t bother, not worth the $
Much smaller in person than it appears. Looks more like a piece of coral than a tree. I got this to display some ornaments for sale at craft fairs, but it’s so small, it looks silly with the ornaments on it. Super flimsy, made of cheap plastic. Definitely not worth $14. Will be returning.
