The small size is great for my small place on my sink counter. I enjoy the way the pik is connected to the base. I love being in control of the direction the pik can be turned, even in my mouth. The tool head container is handy in the top of the pik.I can change the speed of the water if I have some food lodged between my teeth. Another feature that is great is the pause button on the handle of the pik.
Based on my limited use, the Waterpik Platinum Waterflosser WP-100 seems to be a good quality product for dental hygiene. It is of quality construction and is easy to keep clean after use. The water level in the resevoir can be viewed while using the Waterflosser so it does not run dry during a teeth cleaning. The lid of the resevoir can be used for extra tips, and the On/Off Switch and Power Level Setting Dial for water rinsing are easily accessed during use. I would recommend this product.
