I’m happy with the brush. I’ve used Philips and Oral B before and this is definitely comparable for cleaning efficiency at a cheaper price point. The charge lasts a long time and 4 x settings are all good. I use 3 and 4 a lot and don’t have any issue with the noise level or strength that some reviewers with sensitive teeth mentioned. I nearly spent 3 x as much on a rival brush that links to an app but this does the job without checking my phone for info so the only thing I can’t vouch for is longevity. My Phillips lasted years before suddenly refusing ti charge, way past the guarantee window. USB charge and small charge unit are also space saving for travel. Customer support were quick to respond to my email query too. So far all positive after 3 weeks of use.
