Toothbrush Replacement Heads

Following a change to the toothbrush heads from a longer two choice brush head I will no longer be purchasing..
I reordered what I had been using and received a much different brush head.
There is no longer the firmer black brush head .. The white brush is much shorter and much softer.. it has mostly certainly not lasted the recommended three month durability.
Not happy at all since I purchased five new brush heads.
One head has already snapped at the based because they are so difficult to remove and replace..
I am truly disappointed because I really loved the former versions of the brush .
Won’t be back to buy… apologies. especially since this is a rather expensive product.

Love

The bristles are not too soft or hard and I love that it's tapered.
I like that that it's sustainable, and the built-in tongue scraper!

The handle was heavier than what I'm used to but I got over it quickly.
Never going back to my previous brand.
