I've always had deep pockets and my gums have gotten steadliy worse over the years. Flossing is a pain for me because I have a small mouth and my teeth are tight against each other. My husband bought me the Oral B Water Pik about a month ago. Am suppose to use it twice a day but I only have been using it once a day. My gums are no longer sore all the time and I don't seem to be getting as much stuff out as the first couple of uses - I guess because the pockets are getting smaller also. Pretty easy to use although I wish the reservoir was a bit larger as it seems to run out before I am done. I like that it has different tips to for different purposes, the one for deep pockets is soft on my gums but I am not convinced that it really is getting anything out because you have to turn it to the lowest setting and since my deepest pockets are in the back i'm not sure that I have the tip in the pockets. Using this can be a messy experience but it's worth wiping around the sink area just to have my mouth feel better. Pluses would be the ease of getting the tips on and off with the button, I love the pause button when I remember to use it before I spit, and it's a whole lot easier and more effective than floss.
