iFlight 12PCS M3X7+4.5 Anti-Vibration Fixed Screws Mounting Hardware Spacer Standoff RC Screws kit with 12PCS M3 Nylon Hex Nut for Naze32 CC3D F3 F4 Flight Controller FPV Racer

Great quality standoffs. Not too hard and not too soft. I love iflights products. I have bought a lot of stuff from them. From motors to straps to antennas to standoffs, all the stuff is great quality! And their customer service is unbelievable.To the people saying these standoffs do not screw down all the way on top of each other, The purpose of these is to only soft mount the flight controller. There is no reason to stack these ontop of each other and that is not what they are meant for. Buy with confidence.

`I used these to insulate a circuit board carrying two vacuum tube channels which previously was known to be sensitive to microphonics -- audio signal created by vibration of the vacuum tube -- and it works well, no microphonics problems with my circuit.

These work. The metal parts seem to be firmly adhered to the rubber and will not come loose. The rubber is surprisingly flexible. you can bend these about 10 degrees and slightly compress them with small amount of pressure.Although plastic nuts are in the photo the package I did not include any nuts. So four, not five stars. (Sellers need to use photo of the EXACT product, not generic or outdated photos.)That said, these work as expected and I have over 100 M3 nuts already on hand.

Item is just as expected. The ones I got are actually quite durable. I had to give one some hell force threading through a tight hole and it held up nicely. Material Durometer feels right given the application of vibration dampening. Probably not the best if you plan on using it for anything requiring impact resistance as the material deflects quite easily. Would purchase again.

I used the iFlight Anti-vibration mounts to setup my 4 into 1 ESC and flight control board on my 5" drone racers... this really helped reduce vibration into the FPV camera and improved the visibility thru the FPV camera. Additionally, the soft mounts helped reduce shock to the electrical components in the event of a hard landing/crash

The media could not be loaded.  If you fly an F4, F7 (or better if anything else comes out) you're going to want to soft mount your Flight Controller. And these things are the best, don't waste your money or time on O-rings, just get these.

good but the nut is low quality

I like the set because it includes nylon nuts. However as a beginner i did not know that the female side is fairly shallow and you will need rubber bushings and they do not screw together snug.

Very good, got my quad flying as the vibrations were making it crash. The only issue is that the screw holes are shorter than normal so you might need to file down the screw head on the standof below it
