Triple Check Your Measurements. No Margin For Error.
Size: 15 inch, Color: Space Gray
Exterior is exactly 15" wide making for a snug fit of my 14 1/8" laptop. This snug fit was what I was looking for. Any tighter and it wouldn't fit at all. The material is of good quality and the lining is soft. The padding is minimal but should be adequate for everyday use. First impressions are this is a very good quality sleeve. Time will tell.

13.3-inch bag is too big for a 13-inch Surface Pro 11
Size: 13.3 inch, Color: Gray
The bag is very good, but I am returning the 13.3-inch size bag, as it is too big for a Microsoft Surface Pro 11 (13-inch screen). I should have done a bit more digging through the description to realize the size. It would have been better if the pictures showed actual inner dimensions. I have just ordered a 12.3-inch bag. The smaller bag should be adequate.
EDIT: The 12.3 inch bag came in. This bag is perfect for Surface Pro. Great fit! The front pocket holds the power brick and a small mouse, and a bit more space for flash drive or similar.

Nice color and good quality
Size: 14 inch, Color: Navy Blue, Size: 14 inch, Color: Navy Blue
I had originally bought this for my work laptop (MacBook) and it fit perfectly. But now I use it for my personal which is a 13.3in MacBook Air. I like the feeling of the case. I have a crack on my screen and I feel like this case offers more cushion than my previous one. I wouldn’t say this would save my laptop from a fall but I feel more confident as it’s in my bag that it’s getting enough protection. I also like the color and it’s spacious enough to hold a laptop charger, note pad, pens, etc.

Model: iPad A16 11th 2025 /10th 2022
This glass protector was the easiest one i have ever used. went in on easily and only a couple of bubbles that were easy to push out. It seems to be made with quality material and fits perfectly. Got the first one right so now i have a spare.
