Consumer review (

excellent product


I think this lenovo c40/50 series was an excellent purchase. The all in one monitor and cpu made a great space saver for my small work area. The monitor is a great size and\npicture color is perfect. I would recommend this product to family and friends.

Lenovo C40-30 All-In-One


We bought this All-In-One computer about a month ago. This came with Windows 8.1, which we immediately upgraded to Windows 10. All in all, we are very pleased with this purchase. Good performance and a great price! Only features we would have wished...
