หัวแปรงทดแทน Nova Sonic

The fit on my BURST handle is perfect, snaps right on with no wiggle at all. My teeth feel noticeably slicker after brushing, and this head has held up well over three weeks of daily use so far.

These bristles are stiffer than the last brand I used, and the shape fits my mouth better so it actually reaches those back molars. My teeth feel noticeably smoother after just a couple of weeks with this head.

My old brush head was way past its prime, so swapping in this one made a noticeable difference right away. The bristles feel firm enough to really scrub but not harsh on my gums, and it clicks in securely without any wobble.
