I was an early owner. I bought mine in the beginning (first day of released for sale I think). I have gigged almost ever week in rock band or church worship band ever since. My experience has been perfect, Zero issues. ---

I have two of them, heavy studio and stage use, open air gigs, etc. Heat, heavy rain - no problem. I have them since 2020, I think. ---

I repair audio tools and in the past 3 years I have seen more than 6 QCs with different issues like distorted or muted audio out on XLR ports and USB malfunction. Those QCs had been used for a year or two and their owners sold them immediately after repair. QCs with USB port issue need an expensive processor replacement job. It’s a very delicate device and fails very often. ---

4 years until crash First: Drop outs which turned into “no sound at all”. But support was incredible good! ---

I’m on my 3rd QC. First one failed (loud crackling) after 6 months in early 2022, second wouldn’t boot after update in March 2023. Got my 3rd in May 2023 and it has been working fine since. ---

Got mine on late December 2020 , no issue so far. The volume button has always been a little bit finicky, but it is a common ‘issue’ , and the USB cable wiggle a little bit if I touch it, causing Cortex Control to loose the connection, but otherwise it is rock solid. I never moved it, I’m a (bad) bedroom player. 🤷‍♂️ [Previous page](https://unity.neuraldsp.com/t/how-many-of-you-had-quad-cortex-without-issues-for-a-longer-period-of-time-would-really-appreciate-your-input/17145.md?page=2)
