relatively strong water flosser but reservoir is attached which makes drying it nearly impossible [SEP] i have used various countertop water flossers in the past such as the countertop waterpik and the i love the idea of a hand held irrigator and this does work to remove most stuck debris from between the teeth what is nice about this one over the other handheld i tried is that there is very little splash back however i personally do not like that the reservoir is not removable for dryingin the package one reservoir attached to handheld flosser unit one usb cable wall adapter not included one instruction manual one standard jet nozzle one orthodontic nozzle larger brush one pocket nozzle smaller brush one tong scraping nozzle what looks like a spoon i charged the unit fully before use the white light on the side blinks when charging and remains steady when it is fully charged note the charging port is hidden behind a silicone nub below the grip dots on the top of the unit be careful to cover the charging port with this nub when the flosser is in usethere is an on off switch and a mode switch the three water pressure modes are soft standard and massage can be cycled through using the mode switch prior to turning the unit on the jet tip or any of the other three tips gets inserted into the top be careful to make sure it is seated with the notch in the groove as the first time i put it in the hole i did not have it seated all the way to eject press the release button to the left sidethe reservoir is not removable instead water enters through the small opening on bottom through which one has to fill the unit i do not like that the reservoir is attached as i have to drain the remaining water out of that hole and leave the door open for drying also the little button through which the water enters can easily break after lots of use i personally would prefer not to have to use that holei held my mouth almost totally closed during use and tried all three modes i did not have splash back which was very nice splash back is usually typical of almost any type of water flosser so to some extent i was surprised this flosser does work to dislodge most debris between teeth but not everything because it is not super powerful but is powerful enough i am also impressed that the manual is relatively well written kudos to the manufacturer on this normally i feel as if i am reading pig latin when i receive products from china or other countriesin summary my biggest disappointment with this unit is the attached reservoir that prevents me from drying this out easily
