Ok unit for the money. Not that great of quality, mounting holes are random across the unit. Installation guide, manufactured product, and main image provided at sell are complatley different. Please fix this. Is the mounting holes going to provide an issue for installation? Most likely not, but buyers please be aware that the holes are just guides, i did not use them.
