### ⭐⭐⭐⭐ Quality control issues surrounding shipping
*by T***G on July 23, 2023*

Update: I did receive the item finally and I was fairly impressed with it. Just know the scalpel part doesn't lock it's just the screwdriver part. Almost found that out the hard way. It took atleast a good week to arrive. When it finally did I was excited to check it out. I opened the Amazon package and dumped out a plastic container wondering if it would actually be good or not. As soon as I open the box I was greeted with nothing but empty air.. I had to call Amazon to complain about it because there is no option for 'package is ok, product missing from it's retail container'. To top it all off, Amazon requests that I send the empty freaking box back to prove it was empty.. Causing me a huge inconvenience to try to make it to a UPS Store and waste the planets resources to send a box of air back that proves nothing.. I included a picture of the air incase anyone is curious what it looks like. I know many things could have happened but I figure most likely it was a QC issue and they just missed that it was an empty box with air included. If so, it should have been easy enough to check the weight before shipping and really is inexcusable.. So, I'm gunna leave one star, which seems fair, until I actually get something besides a box of atmosphere. I'll report back how it is when I do. As far as features go, I'd say the air isn't very sturdy at all, and neither is the box the air came in. Horrible value too for an almost $50 box of air of unknown origin. Both of those are easily one star. Though, I will say though that the air is extremely lightweight, which makes it a breeze to carry in any EDC loadout, and therefore gets a lofty 5 stars here.
