I have actually purchased multiple holster cases from Blacksmith-Labs over the years. Most of the time I actually prefer the Bruno style due to its simplicity. However, it doesn't look like they make those anymore. I still have a Bruno from when I had the 8 Plus, however, so I'm using that and alternating with the Barrett.
The Barrett is built well, obviously (as is everything Blacksmith Labs makes). It sits snugly in the holster. But the magnet seems a bit weak, and I worry if the holster loosens over time with use that the phone might slip out somehow.
In reality, this is highly unlikely. But it's just a feeling, and I'm constantly checking to make sure the flap is closed. I think it's mainly because when it *is* closed, there's very little feedback to show it's in place.
In general, a great purchase and the clip is perfect as always. But if they switched back to post-and-hole or a larger magnetic post it would be 5 stars.
