What are the best teeth whitening kits for effective results?

Hi everyone, I’m looking for advice on the best teeth whitening kits for effective results. There are so many options out there, and as someone new to this, I feel a bit overwhelmed. I’ve been reading about everything from LED whitening systems to strips and gels, but I’m not sure which ones actually deliver noticeable, safe, and lasting results. If you’ve tried any specific product or method, I’d love to hear your experience.

While searching online, I came across this post that seems to list some of the top-rated and most popular options:

It looks helpful, but I’d still prefer to get firsthand recommendations or tips from people who’ve personally used these products. Are there any particular brands or kits you’ve found effective, especially for sensitive teeth? Thanks in advance for your input!
