Just Right!

I have sensitive gums and most brushes with hard brissles will make my gums bleed a little.
These are very nice and you can tell the difference between the clean that these give and the cheaper brushes. If you're like me though, I'd suggest trying to find the soft version.

I like that the value pack comes with an assortment of colors so that if you are using the same brand/type of toothbrush as someone else in your household, you can easily keep them separated. The ultra-soft type feels like there is hardly any pressure, so it is very gentle, however, I think I would prefer "soft" more. The ultra-dense bristles seem to still clean my teeth as well as I like.
The toothbrush itself is easy to grip with its comfort grip handle and I love the purple bristles.
