Small

This model would be good for traveling as it is not heavy or large and has a small attached water reservoir. I was looking for something that does not need to be filled up with water so quickly.

It's a bit messy, but that would be expected; Be sure to do this over a sink!

Messaging Gums with Water

I have been using Waterpik WP-450 every night since a month ago. I just followed the instructions to use on the website. flossing with luke-warm water is very relaxing and much more convenient than thread floss.

Buy something else

This handheld model has limited functionality. The water chamber is too small to be useful. It only holds enough water to clean one quarter of your mouth per filling. Water goes all over the place when using it. I bought a plug in model to use instead. I don’t recommend any handheld version.

Waterpik -Wish it held another 3-4 oz of water

Easy to use but have to fill twice to do a good job.
