Despite the numerous positive reviews and hype surrounding this product on TikTok, as well as my extensive collection of Ninja products, I was disappointed with my initial experience. When I used the product for the first time, it failed to heat up properly, resulting in me having to reheat the food multiple times to achieve the desired temperature. I thoroughly reviewed the instruction manual and attempted to troubleshoot the issue several times before deciding to leave this review. Regrettably, I have received a defective product. I have given this product two stars because Ninja replaced the defective product, but I have not yet had the opportunity to test the replacement. Additionally, I noticed that this product consistently triggered my smoke detector, which is unusual since my other Ninja air fryer does not cause this issue.
