The product works perfectly as an extended monitor which is why I give it 5 stars. I have a 15in HP Laptop monitor.Pros: 1. The screen quality is better than expected, I was impressed with the clarity and resolution. 2. Overall functionality exceeds expectations as it does provide the "multi-monitor" experience and is very convenient to connect and use. 3. Great for travel - I used this while working during my vacation with family. 4. I am able to use this device daily and not just while traveling, as it provides 3 screens for me to multi-task and be more productive and efficient. 5. Although quite pricey, well worth the value, functionality and time savings.Cons: 1. The clips to attach to the device is quite challenging and needs some rework, but not a deal breaker. 2. This is a quite pricey solution compared to the cost of a basic computer monitor.
