Master Airscrew Stealth Propellers for DJI Mini 3 Pro & Mini 4 Pro - Black, 4 propellers in Set

Excellent quiet

I needed some replacement props. I saw these were advertised as quieter, so I thought I would try them. It isn't a huge difference, but they do what is advertised. I am happy with them.

Not stealth but a lower softer tone. Bigger with a different design resulting in better manuverability in wild or extensive flying

Diffidently quieter. Performance wise, not much of a noticeable difference so it's a draw for me.

Improved airscrew efficiency enhances the power-to-weight ratio, enabling extended flight durations with reduced acoustic signature.

Ordered these as I heard great things about them and the reviews looked great. Arrived today, took them out, all excited to put them on and try them out. Start removal and installation (no instructions because... why would you put a small piece of paper saying "the ones with the half circle indicator go one these arms and the ones without go on the other arms. Boy that was tough). Start installation paying close attention to orientation, left rear on, right front on. Go to install left front and... no. This ain't gonna work. I received three sets of blades with half circles on them (rear left, front right) and 1 set of the non indicated ones. What exactly am I supposed to do with this.... garbage. Also, BTW master airscrew I fixed your crappy demolding work by removing the left over sprues... so, I bought another set of these, maybe with any luck, I'll get something that resembles what I actually paid for and my drone will be functional again. For everyone else, this is the game isn't it, charge just enough so people think you deliver a premium product, then don't deliver on that. It's more hassle to send then back then to buy another set so people will just buy another set. Fair enough, except for its a bad business model because I won't buy again and I hope everyone reads the review and also doesn't order. So sick of this level of quality, how hard can it be to get the right thing in thr bag. This is why 1 star review. Garbage. Complete garbage.

Not much quieter than the original and didn’t notice any significant flight time increase but they worked well and looked better than OEM

These work great on my mini 4 pro. Don’t know if they are quieter, just lowers the pitch tone. But they work great!
