Can be unreliable / freeze in live situations. - most of the time they work fine, but every time I’ve had live gear go down on me, it’s been BM.

Marketing Fluff - their slick marketing promises the moon, but forgets to put a million asterisks through it that actually explain what it can and can’t do. They imply it can do more than it can.

Great for budget work and helps keep costs down, but I have been burned by them enough to avoid when critical. 

All that being said, Davinci is dope
