I really like the Oral-B Manual TB. I bought the toothbrushes by the dozen for two reasons. Why buy toothbrushes every couple of months when it is time to replace them? And it was definitely cheaper to buy in bulk (online). However, I did notice this time, as opposed to the first time I bought them in bulk, that the stem of the toothbrush is more slender. Not hard to hold, but just less weight and it just seems a bit cheaper in quality. I don't think I am imagining it as I compared it with the prior brush I had (and just threw out because I got the replacements) and the quality was just not the same. I will continue to use Oral-B, but I am going to keep my eye on the quality for future purchases. I may or may not purchase them again. The price was right, but really at what cost? The bristles seem just as good and effective.
