Overall, for a $15 product, it's good enough until you get nitpick-y.I don't exactly know what I expected out of this. For context, I have a MacBook Air 2015 so its a 7 year old product but everything runs perfect. I mostly use it for web browsing, music, and just everyday stuff like shopping online. I got the green one since I've been digging the earthy vibes lately to match with my dark wood table, and I just like green in general. Installation was relatively easy, everything clipped in nice & was able to do it no stress within a minute or two.Keep in mind, it's only been a day since I bought it and I've already noticed the flaws of the product. After installation I put everything in my laptop bag and went on my day, took it out to do some studying and already I noticed the smudge on the case. I don't know about anyone else, but personally speaking, I like to be neat. In my opinion, it goes a long way into how people see you as a person.It wasn't that bad at first and thought maybe with some alcohol cleaning it'll come off. Not only did it not work, I think it even made it worse. I looked online and found people use toothpaste(?) to clean the thing. Didn't bother trying, if alcohol can't remove it then I give up.One feature I always liked about apple products is how well made they are. I don't know much about other laptops, but with my Mac, unless I really tilt the laptop in a really aggressive angle , the screen won't pull back or forward at all. Its not too hard where I feel like Im applying too much force to open the thing and not too loose where it just moves back and forth. It definitely works if you have the laptop in a stationary position on a table or something. Now if you're asking why I'm tilting it in the first place, I use my laptop when I'm on my bed. so I generally move the laptop around if I want it on my lap, side of the bed or even just on the bed if I feel like criss cross sitting.But ever since I put the top case on, the screen would push back and forth with ease on slight angles. it made a $1000 product (at the time) feel like a $500 product. Now keep in mind, my Mac is 7 years old with close to 300 cycles of usage. So the hinge holding my screen could just be giving out. But as soon as I took off the top case, I noticed an immediate difference. At this point, as the picture above depicts, it now has crazy smudges on it and I decided to just completely remove it, I left the bottom case and the keyboard overlay on as it doesn't really affect my usage and its something I can be okay with it being dirty (for the mean time).As of right now, I decided to buy a dbrand green skin and a leather sleeve for it. the shell Is definitely more secure than a skin but my only concern is really just scratches on the aluminum case and the fact that I know the skin won't add too much weight where it affects the ergonomics of this laptop. The odds of me actually dropping my laptop is close to zero (knock on wood). One could argue that the skin alone is almost quadruple the price ($25-$50 depending on the kit u get). I'm getting the full kit that also comes with a trackpad & palm-rest skin. And the sleeve alone is $90 (leather). So yes pricey, but I'll pay for anything with peace of mind attached to it.Overall, it's a $15 product that will serve its purpose, but if you're someone like me, I wouldn't recommend it at all. if you can afford better, buy better.
