Those pics always do the rounds on the internet - usually posted by somebody who paid 3x the price for the original wheels. I have been selling Rota Wheels for the last few years and have never had an issue like that (after selling 10s of 1000s of wheels). Notice how it doesnt show the full picture... just zoomed in on the wheel.
There are also photos of destroyed Work, Advan, Volk, Enkie and 5Zigen wheels out there if you look hard enough.
We had a guy that hit a huge kerb at over 100mph head on, popped a hole in 2 of his tyres the size of a fist and yet the Rota wheels were spot on (and from kerbing)
I run Slipstreams on my daily driver EM1 coupe - never had an issue
