great compact unit not as strong as others though [SEP] our last water flosser died so it was time for a replacement this unit is very compact i was actually shocked when it came because i thought there was no way it could fit in there lo and behold it did although this is a permanent fixture on our sink it could easily travel with us if we went anywhere being a compact travel friendly water flosser i was surprised at how much volume it can hold if you cannot tell i am really impressed by the compact ability of this water flosserit comes with a variety of tips enough to make this usable for a couple as my husband and i share it it is very easy to use the one call out if you have a more traditional water flosser is that this is a rechargeable unit it comes with a charging cord usb but no base so you will have to grab one of your existing ones and let this charge for about hours so you cannot use it straight out of the boxthe only complaint i have is that even at maximum pressure it is not as strong as our previous one it does work well enough to get any extra stuff out of your teeth after brushing however it is not the strongest water flosser my husband would like something a bit more strong but that is really the only complaint we have
