Review on Replacement Waterpik Compatible Irrigator Orthodontic by Samantha Allen

I bought these as a direct replacement for my Waterpik Ultra WP-100W. I am disappointed and will not buy it again. Unfortunately, while they can work and "snap" in a mount, they rotate when they shouldn't. This makes it difficult to control the jet's visibility. The original tip, which is difficult to see unless you look closely, has a faceted edge just below the colored plastic piece. That means it has flat edges and is not round. In cross-section it looks like a stop sign, but maybe 15-20 pages. These edges help it lock into the handle so it doesn't rotate. Unfortunately, this area of the replacement tip leaves too much wiggle room. It just doesn't fit and can still rotate. The diameter is less than a fraction of a millimeter. I tried another tip from the same pack, the problem persisted. I put the original WP tip back in and there was no problem. It's weird that they probably produce thousands of these in the factory and can't find the time to do it to the right tolerance.
