Where do you get your information? I haven't heard of any issues what so ever with the QR props. I saw one post where the base cracked.... Could have been a material defect or over tightening.... Hardly a major issue.
There is a thread about it on Inspire Pilots forum,

Personally, I don't want any props (responsible for keeping my 4k bird in the air) to have the name "quick release" associated with them, but that's just MY preference.

(I am a big fan of the prop locks and have plenty of time to take them on and off when needed)
