Not bad
Color: Orange
It’s a cool charger. It seems to work as advertised, as in it trickle charges when needed or pushes the power hard when you need it. The only complaint I have is the animation lasts a little long and there seems to be no way to manually turn it off when you want to. When plugging in my phone at night, it’s annoying to have that much light for so long when trying to sleep. That all said, I’d buy it again if this one failed, I do like it, just that one annoying thing.

WELL WORTH THE MONEY. NO QUESTION
Color: Orange
COOLEST LITTLE AI CHARGER IVE COME ACCROSS. CHARGES MY MACBOOK NEO AND MY PHONE. IT TELLS ME ON THE CHARGER, WHAT DEVICE IS CHARGING, WHAT WATTS ITS PUSHING THROUGH, AND SAYS ON THE CHARGER, HOW LONG IT WILL TAKE TO GET TO A FULL CHARGE.

Best laptop sleeve on the market — and I've tried plenty!
Size: 13.3 inch, Color: Black, Size: 13.3 inch, Color: Black
As someone who reviews products regularly, I have pretty high standards and I don't hand out 5 stars easily. But this MOSISO sleeve? Completely earned it. I've tested a lot of laptop cases over the years and this one genuinely stands out from the crowd. The quality is immediately noticeable right out of the box — the material feels premium, looks sleek, and has held up flawlessly through heavy daily use. No pilling, no wear, no disappointment. The fit on my 13-inch MacBook is perfect. Snug without being tight, and sliding the laptop in and out is effortless every time. The zipper is smooth, the padding is substantial, and it slips into my bag without adding unnecessary bulk. I've gotten multiple compliments carrying it around at coffee shops and the office. I also accidentally knocked my bag off a chair recently and my MacBook came out completely fine — so the protection is definitely real and not just marketing fluff. For the price point, the value here is genuinely hard to beat. I've reviewed sleeves twice the cost that don't come close to this level of quality and finish. MOSISO really delivered with this one. If you're on the fence, trust me as someone who does this regularly — it's absolutely worth it.

PURRRFECT
Size: 16 inch, Color: Deep Teal
I purchased this item on April 12, 2026 and received it on April 16, 2026. It is just PERFECT!! The right size, the color teal is just awesome looking, the quality of the material is strong and durable, the lining inside is well padded to protect the laptop, the zipper glides easily and very strong. The pocket outside has ample room to put miscellaneous items. I love it and I love it!!!! Go for it! It is worth the money.

Good-looking case that is well made
Size: 13.3 inch, Color: Bright Rose
This case is well-made. The material is non-slip, the zippers are easy to use, the stitching is quality, and the case is a perfect fit for my 14" MacBook Pro M5 even with a Speck protection case installed. All that being said, my favorite feature is the color. WOW! It definitely will not get lost in my office or in a dark backpack or briefcase. I'm not sure how I'll use the front pocket. Off the top of my head I'll probably put a pen, slim notebook, and business card. I'll update this review if this doesn't work for me. One more thing...I also bought the 13" Chartreuse for my Citrus MacBook Neo that has a MecBevia protection case. Perfect fit!
