Very happy with the tooth powder, definitely some whitening effect and teeth feel smoother. I use another brand normally which i was also happy with but weluxia is cheaper for twice the amount and equally good, tastes fine, will definitely purchase again.
So far so good. It's only been a few days but my teeth feel clean and shiny, and it's dealing with sensitivity well. Arrived in good time and hopefully will last a while. The mint flavour isn't overwhelming at all, and there is no frothing, which is good as I think that means it's coating all the surfaces without ingredients that block the process.
