Just went through a similar wobble experience and discovered multiple cases in
vevor reviews discussing blade stability problems. One suggestion mentioned that combining blade photos showing the wobble with measurements of the shift helped their team diagnose more quickly. I created a submission including close-up images, specs of the blade diameter and arbor looseness, and explained how many rotations per minute it shifted visibly. Within a few business days, their technician replied with a video guide on tightening the arbor nut and aligning the blade properly—and even offered to send a replacement part free of charge if issues persisted. Clear, measured evidence sped up their support and prevented guesswork.
