Yes, it's travel sized, but it's annoying.
The size of this "Water Flosser" is good for traveling but I felt there were some design flaws that made it annoying to use. 1) The tip was a challenge to lock in place. The distance from lock to unlocked is tiny & it was not easy to get a good grip on the tip. No fun when you turn it on, the nozzle flies off and you, and bathroom get wet before you can turn it off. 2) Filling the reservoir would have been easy however my sink is a smaller basin and I couldn't hold the flosser flat to fill more than half-way, directly from the faucet. (I ended up just filling a cup and pouring the water in.) 3. Even with reservoir completely full, I ran out of water well before I was done cleaning.  I liked the idea of not having a bulky tub of water taking up space on my bathroom counter, but don't think this was the answer.
