Review on 🎓 Hopkins 08525 Advanced Graduation Level by Jeremy Flint

I like the simplicity of these devices. I have one in the front and one on the side of my RV. I used the included double sided foam tape to attach it to the van so I didn't have to drill holes. However, the tape allows for slight movement that can confuse actual levels. I used a long spirit level when installing. I use my own 4 foot spirit level to make sure the trailer frame itself is level. Then I attached these two to my trailer using my own bubble level. The site is pretty accurate. However, the front is slightly offset, although the unit's body says it's level, and upon confirmation, the trailer frame is level. In this way, I quickly "get closer to the goal”, so to speak. I would recommend adding an extra double sided foam tape to keep it from moving after sticking to your surface.
