Review on COYU Portable Level，Cross Horizontal Selectable by Centerfold Trapkin

This portable level is a great addition to any industrial and scientific setting. It allows for both horizontal and cross measurement, making it versatile for a range of applications. The accuracy of the readings is impressive and the digital display is easy to read. The only downside is that it requires a steady hand to get consistent readings, but with some practice, it becomes second nature. Overall, a reliable and useful tool in any dimensional measurement toolkit.
