On a personal note, I have done their Professional Effects and was very pleased. I recommend taking before photos so you can see the difference, as starting out it can go pretty subtle and not seem as if it is doing much.

I had very good results with Professional Effects Twin Pack, been probably I think about 6 months and still going strong 👍
Only "issues" I encountered :
-if you have (I don't know the official name) fluoride spots on teeth, this will brighten those up first before rest of tooth catches up and evens out (but they did even out pretty quickly!)
-if you aren't paying attention and let it sit on your gums it could cause a minor burn, but I only had that happen once to me during the entire period.
