Review on 🔩 MakerSpot Raspberry Pi Nylon Standoff Kit: 210pcs Screws, Nuts, Spacers for DIY Raspberry Pi 3, Zero, FPV Quadcopter, PC Mods by Chris Laznovsky

Very, very bad. I have a robotics project and thought I would use these to hold my modules. Nuts slip off bolts. If you hold one of the stands and pull out a fully threaded nut, you can usually pull it out. I had to order a whole new set because of the miserable quality. This is especially frustrating because it's not really worth returning such cheap items because most likely you'll only get around $4 back, so don't try and think you can return it if it sucks.
