so much smaller than the description [SEP] when i bought this i was considering this or one of the all in one handheld glad i went with thisas you can see in the picturethis is much more compact than the photos the company provides not super compact but fits on my bathroom counter nicelyfor setup charge first you have to take the cable out of the back to get it to work the tank looks pretty small but it goes a long way i use this about every other night and i have not recharged the battery or added more water except when i wanted the water to be warm i have sensitive gums and the warm water seems to be less harsh than cold wateri have stayed on the lowest setting and it gets out a lot of gunk this will make a mess if you close your mouth then you are pretty good but if you open your mouth water goes everywhere there is a button on the handle to turn the water off maybe i will use it when i clean my teeth this is pretty loud when you run it not sure if i would want to use it with other people too close but if you want to travel with this its pretty compact and has a little carry bag most of the items store in the lid so that is pretty handyif you have been looking for a water pik type device give this a try use if for a couple weeks and see what you think
