Casiii Universal MacBook Keyboard Cover

I just received this keyboard cover for my Macbook Pro 13" by Casiii. I received this product for free for my fair and unbiased reviews. It's basically a universal cover for all Macs, and it's okay I guess...
Let's first look at some pros:

1. It's incredibly thin! 0.1mm
2. It's washable
3. The molds fit the keys (too well)
4. Durable
5. Food proof!

However there are quite a bit cons:

1. It's really hard to type fast and efficiently with it on
2. It slows down typing A LOT
3. When I hit some keys, it takes a while before it pops back up again.

Looking at that, I can tell you that it's a good sometimes cover for short typed things, but for a long term paper, or email take it off. Another thing to mention is that they basically took this design from the Moshi ClearGuard. Looking at the website, what Moshi wrote about their product is also on this box, so while the Moshi one is almost $30, this one's below 15. Overall, pretty good.
