Review title is Small enough I can brush properly without a gag reflex but "sonic" takes getting used to. [SEP] Oh, my goodness, the size of the toothbrush head..... I can actually brush all of my teeth without triggering my gag reflex!<br /><br />That alone should get it five stars, but.....<br />Philips wasn't kidding about the &#34;Sonic&#34; part. That part will take quite a bit of getting used to.<br />And while I like that I can use mouthwash in the air flosser instead of limiting myself to water, sometimes I prefer a steady stream of liquid over the &#34;pulses&#34; this thing uses. I'll still use it on occasion, I just won't be getting rid of my Waterpik any time soon.
