Excellent product! The AI assistant works perfectly and the voice recognition is amazing. Highly recommended!
Very impressed with the build quality and features. Setup was easy and it integrates well with all my smart home devices.
Good product overall. The design is sleek and modern. Only minor issue is the initial setup took a bit longer than expected.
