It’s essential to check local laws before purchasing, as I didn’t want to invest in a product that could lead to legal issues down the line.

Installation Options

When considering installation, I had a couple of options. I could either tackle the project myself if I had the necessary skills and tools, or I could hire a professional. I weighed the costs and benefits of both approaches. If I chose to DIY, I researched installation guides and watched videos to ensure I had a solid understanding of the process.
