A pad that just delivers
Color: Black-31.5"x15.8"
The item came in minimalist packaging. The mat came out and was ready to use immediately. The build quality is great with no distortions in shape that I had with a lower quality gaming mouse pad I was gifted once. The wireless charging just worked, and true to word, if I place my phone just right on the spot it engaged turbo wireless charging.
It felt great, smooth like a high quality mouse pad, just huge. I can fit my laptop, keyboard and mouse with room to spare.
Don't regret decision to buy.

Check to see if you need an adapter
Color: Black-Phone Holder-31.5"x15.8"
Very nice pad, good size and neat looking. Charges the phone and do not need a separate charger.
ONE WORD OF CAUTION. I expected to be able to hook it up and use as delivered. BUT, expecting a USB
compatible wire that fits into a normal plug, I needed an adapter to be able to plug it into a plug adapter.
The ad needs to be able to highlight the fact that you may need an adapter.

Works great; As Advertised.

Love this pad with wireless charging. Doesn't come with a charging brick but does come with everything else you need.

Mouse Pad Charger
Color: Black-27.5"x11.8"
I absolutely love the mouse pad. It fits my 17.3 inch laptop nicely and my mouse. It's great for charging my phone next to me while I work. Unfortunately, it does not work for the Air Pods. It must be for an older version. Nonetheless, it's still a great buy.

A good product
Color: Black-27.5"x11.8"
Size is accurate and this is important in my situation as I use a pull out key tray and wanted edge to edge coverage. Depth is good but in my case I would have liked a deeper dimension as an option. Phone charger works well, the mouse slides smoothly
