I looked at the original part and the new one and I couldn't see any difference with the naked eye. After installing it was too long to press and I basically had to press a little. It's disgusting that Dyson doesn't have an inexpensive replacement option as we're more into those products. Am I using them? Yes Does it make noise and bother me with the usage time? Yes, but since the only worthy replacement for a Dyson is the whole head, I'll cross that bridge when I get there.
