    I never write reviews, but in this cause I feel justified. I purchased the 9900 on November 28, 2025. It stopped working 28 day’s later. Best Buy would not let me return it because it was past 15 days. Trying to get Phillips on the phone is near impossible. Funny Best Buy didn’t mind taking my money, but not standing behind anything. I’m a long time customer spending thousands of dollars with Best Buy. I would never recommend this product to anyone!
