I would rescue it from a fire even if it were empty. I'm kidding but I do like this sleeve a lot.
Color: Orange, Size: 13-inch for New MacBook Air & Pro
Fits perfectly. Superb padding. The corner padding inspires confidence-not that I want to test it! The orange color is-chef's kiss-beautiful. A perfect contrast to the midnight color of my MacBook. I could gush about that stuff all day. But you all want to know about the other stuff. Zippers: Two YKK no snag bi-directional closers for the main opening and a solo no snag YKK for the side pocket. Outside: Feels like tactical nylon type fabric. I haven't and won't intentionally test its stain resistance. But I suspect it would clean up just fine. Interior: A very soft microfiber like interior covering an odor free padding that is firm yet forgiving. There is a recess you push your laptop into making for a snug fit that, like I wrote earlier, inspires confidence. This sleeve is larger than some competing brands but seeing the recess in person explains why. Having touched on the size of this sleeve, it maintains the svelteness of my MacBook Air. Yes, it is thicker than some other sleeves, by a smidge. However the additional protection suggested but that smidge, that minute extra ish is worth it to me. The sleeve fits in my travel backpack, so that's all good. Lastly, I would consider putting a tablet or phone in the sidepocket but not anything that would concentrate the any energy that dissipates during a fall. Had I designed this product I wouldn't have included the side pocket. It's great for documents and thin things but the sell page suggests chargers. That seems like inviting risk. You do you.

Best purchase
Color: Air Blue, Size: 15-inch for New MacBook Air
This is a very nice and cute laptop case. The inside is super soft, which helps protect the laptop well. I also like the front pocket because it can hold a few extra items like cleaning wipes or my laptop stand. The only downside is that it’s pretty bulky, it adds about two extra inches around the edges for protection. For reference, I use a JanSport Cool Student 17.5” Backpack (Navy) that fits a 17” laptop, and this case takes up almost all of the laptop compartment lengthwise. It definitely provides good protection, but the extra bulk is something to keep in mind if you’re trying to fit it into a backpack.

Solid choice for fuse holder
Size: 300A Fuse Holder
It’s awesome, solid connections for running 0 gauge wire. No issues after using for months! Might upgrade to using 0 gauge wire ferrules to use with this but for now everything is working well.
