考虑到低廉的售价，我们对C300真的没有什么可以挑剔的。尽管在设计上十分节省成本，但它的机身质量很好，放在腿上使用也十分舒适，不会在运行中变得很烫。它的输入设备属于可以接受的水平，没有什么大问题。不过它的LCD屏幕就十分一般了，不过提供了不错的亮度和磨砂的表面。它的性能在日常使用中十分不错，与其他的Chromebook一样，它在开机，关机，睡眠/恢复时都非常迅速。作为一台入门级设备，C300在大部分方面都做得很好。

不过当然了，多投入数百美元你可以得到个更好的传统笔记本（或者联想ThinkPad Yoga 11e Chromebook如果你喜欢的话）。而最主要的是，它仍然是一台运行Chrome OS的设备——这意味着它在使用中又很多限制，并没有完全得到开发，尽管在一些主要方面已经有所改进。它缺少完整笔记本电脑所需的很多重要功能，从对打印机的支持、完整的离线使用功能、到对USB设备和NAS协议的支持都不够完善。因此，C300不太可能独立作为一台主要设备使用，而不需要传统PC或MAC的帮助。不过作为辅助设备，它是我们至今测试过最均衡的Chromebook之一。
