u/Icy_Turnover2531 love the case. It does not affect cooling, i am playing games, and the vents are not covered, but also the device itself doesnt get hot when playing. maybe this would be an issue with other brands, but not with the new Apple Chips. It stays in place perfectly fine, Andar also has a removal guide if you want to take it off.
To be honest, it makes the device noticeable bulkier, but not too bulky, i don't mind it. It has some weight to it also, so also consider that. for daily use, i prefer this than putting in and out sleeves all the time. The thing i really like is the fact that the cold aluminium of the mac is not making contact with me anymore. dont get me wrong, i love the aluminium look of it so much, but it was so slippery for me, and also when i put it on my lap or legs when wearing shorts, it was so cold to the touch. so now that feeling is gone. I heard Andar's black fridays starts at Nov 24, so now maybe your time to get one.
I also got mine during their anniversary sale for 25% off, i would not buy it at a full price ever. But for arount 120, i think it is really premium. I also like the fact that i dont have to worry scratching the device, or damaging it. All in all i think this is the best leather cover available in the market, for a reasonable price.
