Is there really enough water to fully brush? Is the floss head as floppy as many claim?

I have the WP Flosser-450, portable, no batteries. Very happy with purchase and WP gives it a 2 yr warranty. Amount of water depends on persons preference. The reservoir holds about 7.6 ounces. Sometimes it is enough for me, sometimes it isn't. But no worry since it is really easy to fill it again and double your pleasure. My floss head is secure and strong with more than enough force I need on setting Low. I just tried setting High and it is secure also.

What is the Power supply:Input: AC 100-240V ?? 110 VAC only? Thanks.

The power rating is 100 to 240 VAC. This means it works on 100 -120 VAC mostly in USA or 220- 240 VAC mostly in Europe. Kind of like a cellphone charging block, works on 110-220 VAC

voltage of the recharger?

This is what is says on the AC Adaptor charger: Class 2 power supply Input 120 V AC 60 Hz 2.1W
