Colgate optic white

First impressions
Prefer medium bristled toothbrushes but I do like this one
toothpaste works well
good grip on toothbrush
tastless paste
leaves teeth feeling a bit gritty at first
after an hour or so teeth feel smooth


After two days
Teeth have brightened
not a wow that's bright but definite whiter


something to watch...
after drinking soda it stained my teeth? could have been lighting in the room.
i have whiter spots at the bottom of my teeth and those were white but the rest of my teeth had a slight tint to them.


downsides
take out the gel stick before brushing... can be bulky.
