Bristles killed my gums!  Too firm!
I did give these 4 stars initially but now I've taken it down to two.  The first shipment of these generics I received were exactly the same as Oral-B name brand.  The latest batch were way too firm!!!  The bristles are virtually non-compressible!  The only thing they are good for is scrubbing my jewelry.  They tore up my gums & made them raw. I couldn't press them against my teeth at all so consequentially, didn't do a good job cleaning any surface that wasn't flat.<br />Will DEFINITELY not purchase again!
Rating: 2 stars
