Very well-made, nice valet, solid wood with a silicone surface
I really do love this white BROWN wooden valet Tray. It has taken it place right next to my bed on my nightstand. Currently it contains a flashlight, my watch charger, earbuds, remote control, and a walkie-talkie. They all fit perfectly, it really keeps my stand, neat and clean looking. I like these trays because they look so much better than things just laying randomly across your nightstand. It saves things from rolling off to the back of the nightstand against the wall, where I have to flex like an acrobat to reach them. These are perfect for any works surface as well. These would be welcome in the shop. I'm sure they would be great for a teacher, a kitchen a professional at their desk. Just about anywhere you need to put small items and store them temporarily.
One of the best things about it is that the bottom or at least the inside surface where you place items is not wooden. It appears to be some type of a silicone so you don't hear that wood sound when you drop things into it. It's soft and things don't roll or slide. It holds them in place exactly where you put them. The bottom came with four felt pads that you can stick on the bottom before you put it on your nightstand or wherever you're putting it. Keeps it from scratching any wooden surfaces. It has a nice rounded edges are very clean dark wood look and a great silicone mat on the inside, this is perfect for your nightstand. I really do enjoy it. Comedy no assembly required. It's well-made and it's a sturdy piece of wood. I highly recommend it.

Holds hubs personal items nicely.
This is a decent sized wooden tray for the price. The manufacturer took care to package this nicely so it was not damaged in transit. All the material used on this tray seem to be pretty decent. The color is very versitile. The wood feels durable and not a soft wood that would easily scratch or dent. The faux leather lining is very nice and makes it quiet when hubs puts his keys down. This tray comes with 4 feet which one must apply by simply peeling the release paper and sticking to the bottom of the tray. This is nice so the tray does not scratch the night stand. Honestly, this tray is very versitile as this can definately be used on an end table in the office or in the bathroom to corral items on the counter top. This is a decent product at a very fair price.

Looks good and works great
Color: Wireless Charging
I put this on my desk at work and it is the perfect size. I keep it unplugged when not actively charging a phone, but the charger works well with an iPhone 15 though it seems to charge slower than if I use a charging cord, but that is not a big deal. I do have to take the case off the phone because of the type of case it is. It was easy to set up and I do take the cord out when not charging the phone. The mat itself is soft, does not have any strong odors even when first opening the package, and makes my desk look neat. Seems to be pretty thick and sturdy and would hold up to normal, every day use. Accidental spills were easy to clean, just wipe with a damp cloth and brush away any lint.

Great
Color: Wireless Charging, Color: Wireless Charging
I bought this wireless charging mouse pad, because my phone isnโt charging anymore using the USB, plus I need a new mouse pad, the wireless charging is super convenient, just drop my phone on the pad and it starts charging fast 15W.
The surface of the pad is really smooth, perfect for both casual use and gaming. My mouse glides like butter, and it's big enough to hold my keyboard and mouse perfectly. It also stays in place thanks to the non-slip backing.
One of my favorite things is the foldable phone holder. I didnโt think Iโd use it much, but it actually comes in handy when Iโm watching videos or just keeping an eye on notifications while working. Plus, the whole thing looks pretty sleek and would actually make a solid gift.
Overall, definitely worth it for anyone who wants to tidy up their desk setup and the wireless charging is super convenient. Easy to use, durable and easy to clean.
