"Wish I could give 0 stars. A worker in one of their company vehicles was in a left only lane, while I was in a lane to go straight. There was no room for him to merge into my lane (traffic was a bit heavy). He continued to go into my lane, without a care and almost completely rammed me off the road. I am in a small car and the truck could’ve done severe damage in that moment. If this is how your employees are on the road, I don’t want to see how they are in the work field."

"I gave the incredibly specific guidance of "just please make my wifi WORK" and got in return an incredibly skilled installation, optimization, problem solving and education on how wifi, in fact, works. He validated the best network provider in our area, ran cables, tested connections, and when he left the network was screaming. I had some follow on questions (which ended up being the ISP and not his work) and he responded quickly, clearly and helpfully. He was incredibly professional, reliable, well educated and willing to make sure the job was done right.

Stereo and Home Theater Systems questions, answered by experts

Costs depend on system size, equipment type, and wiring complexity.

Yes, installing a home theater is worth it for the opportunity to create a movie theater-level experience in your own home, especially if you want to upgrade how you entertain guests, watch movies, and play video games. Your budget determines the size and capability of your in-home theater, so the value you derive from the home theater you can install depends on your needs, expectations, and how often you use the space. Consider choosing your home theater features based on the value they’ll bring to users to ensure you invest your project budget wisely.

Regularly dust speakers, check for loose wires, and update software for smart systems.

Consider the room size, speaker wattage/output, personal sound preferences, and budget. High-quality speakers with appropriate power ratings for your room will deliver a better audio experience.

DIY is possible, but professional installation ensures optimal speaker placement and wiring.
