Such a good buy! Great price
Style: 256GB | Magic Keyboard, Color: Citrus, Set: Without AppleCare+
The power this little MacBook has and how fast it runs is everything. The performance is top tier for what I use it for. Battery life is also great. If you been wanting a Macbook but don’t want to spend a lot of money. You should get it! It holds a little weight to it but nothing too crazy.

came in pretty fast. within a couple hours, i ordered at 6am, received it by like 10:20am, its so smooth, the only downside i have is it only has 2 ports, c type, so i ordered an port extender, this is my first apple macbook laptop. so far i love it. it runs roblox really well. been watching a movie and playing with split screen. hasn’t overheated at all. battery life is amazing, been using it since 10:30am nonstop it was at 75 when i set it up, it current now at 32, arrived in great shape, no scratch or breakage. and it’s such a pretty pink blush color. def recommend.

Ridiculously satisfying!
Size: iPad A16 11th/10th, Size: iPad A16 11th/10th
YES! I am completely obsessed with the SPARIN Screen Protector for iPad! From the moment I applied it, my screen looked crystal clear and felt silky smooth like butter under my fingers. The fit is absolutely perfect for both my 11th and 10th generation iPads, hugging every edge without a single bubble or misalignment. I love how responsive it is... swipes, taps, and even intense drawing sessions feel flawless, like my iPad is brand new again. The protector is tough and scratch-resistant, so I can toss it in my bag without worrying about keys or pens ruining my screen. I also love that it doesn’t mess with the display brightness or clarity, so everything still looks vibrant and sharp. Applying it was super easy and stress-free, which honestly surprised me because I expected a million bubbles or frustration. Five stars all the way for a screen protector that makes my iPad feel safe, sleek, and ridiculously satisfying to use every single day!

Happy With The Quality of This Screen Protector
Size: iPad Air 13'' M4/M3 /M2 & iPad Pro 13'', Size: iPad Air 13'' M4/M3 /M2 & iPad Pro 13''
This is my Amazon review for the SPARIN Screen Protector for iPad Air 13 Inch M4 2026 & M3 2025 & M2 2024 (8th/7th/6th Generation) & iPad Pro 13 Inch M5/M4 (8th/7th Gen), Case Friendly, 2 Pack Tempered Glass, Support Apple Pencil. This is an easy to apply screen saver with few bubbles to smooth out. It is very clear and covers the screen perfectly. I literally can only see it is on because of the cut-out over the camera. It is very thin and transparent. My iPad also responds precisely the same to my touch and pencil, so the touch sensitivity feels great. I am very happy with the quality of this screen protector so far. It seems to be a good quality screen protector. Thanks, Amazon.
