Would Not Recommend
I've noticed SwitchLabs being recommended quite a bit lately, and I'm honestly skeptical of some of those recommendations. Some seem to come from inexperienced learners, while others feel more like promotional accounts or bots than genuine users. It's worth questioning how authentic these endorsements really are. Others have noticed, too.
Beyond that, I'd be cautious about spending money on their training. Most of the labs I've seen are extremely basic, incorrect, and completing a bunch of simple exercises doesn't necessarily mean you're developing a real understanding of networking. That can give beginners a false sense of confidence, especially when they're preparing for certifications or actual networking jobs.
I'd recommend sticking with established resources like Jeremy's IT Lab and the other trusted materials frequently mentioned in this subreddit.
Don't assume a resource is legitimate or effective just because you keep seeing people recommend it. Popularity, especially when the recommendations themselves seem questionable, isn't proof of quality.
As an experienced engineer I would highly suggest people learning stay clear.
Edit: Does anyone know how to get ahold of MODs beside MOD mail. They appear to be absent for a while.
