I've never used an at home kit, but I bought a Groupon to get Zoom whitening done in an office for ~$150. Totally worth it and it made a huge difference. It's been about two years and my teeth still look great.

I swear by the aquafresh trays. Yes, they are messy and horrible but I have had so many comments about how white my teeth are, even from my dentist. I drink a lot of tea so I use them every 6 months or so to get rid of the stains.
