Review title is 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 can't tell, I'm really impressed by the compact ability of this water flosser.<br /><br />It 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'll have to grab one of your existing ones and let this charge for about 8 hours -- so you can't use it straight out of the box.<br /><br />The 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!
