Review: Nice kit to have for when you need it - I used this standoff kit during a recent SFF PC build and it worked perfectly. I needed 20mm male to female standoffs to mount my GPU higher in the case and the included 20mm M2F piece was perfect. This is one of those kits that's nice to have when you need it and probably something every PC builder should have in their toolkit.

### ⭐⭐⭐⭐ Need more smaller screws

Works well, even though I needed smaller length screws, they are nylon so I was able to cut the longer ones to the required size. Not real strong
