I did enough research before purchasing this product to know exactly what to expect. I had several options but settled on the Dig-Pas DWL1500XY based on varying customer reviews and the price compared to other similar products. App setup and initial instructions that are easy to follow. The product itself feels well built, durable and easy to use and read from its own display when you don't need an app. With the app and the Bluetooth function, I can make adjustments out of level myself while looking at my phone's display. I would recommend this to buyers who know how to set up hardware running applications. You can still use the (limited) layer without a phone by reading the display on the layer itself.
