Purchased from Amazon, and the set I purchased came in an unbelievable stout high quality presentation box... and included their new Quick Disconnects, which are machined aluminum spin-off... claim self tightening in thread pitch. The set with the quick disconnects indicate they work with X5 and X5R... the mounts raise the props a few mm. I have the I1 X5R and they clear about the same as the 1345 OEM props.

As an experiment, I purchased the T-Motor, Ultimaxx and the XOAR carbon props.
I'll take a few Db comparisons and mount up a multi-sensor array to measure acceleration, forward vector acceleration, axis rotation (yaw / pitch) and various other variables in comparison to the DJI Props when the weather gets above 40F.
As others above indicate, informal perceptions of ears & eyes... they're either lower in Db or a lower frequency, because they do "sound" quieter... Db tests will verify. It's indicated in reviews the stiff carbon improves response & handling... they do "feel" to respond initially quicker, not sure about after the initial movement. I tried them on a day with 25-40mph winds, took off with side wind.... the Inspire did drift sideways, but was responsive in the cross wind. In playful flying... coming down fast with a quick flair up to hover definitely brakes faster and visually looks like it flairs upward higher for the estimated same amount of stick command.
Everything from the quality presentation box, machined quick disconnects, and the carbon finish; it is a very nice looking product. If it doesn't improve the performance, it sure looks nice! LOL!
Have not tested video, but to my understanding all carbon props had an issue with the Inspire & associated vibrations unless there was a motor mount plate or something between the motor and the prop. The Quick Disconnect hubs provide that separation.
