Works great!
I bought this for husband since his original (model wp-100) waterpik hose had gotten a small hole for some reason. Instead of buying a new system,I figured I'd just buy the hose since that's the only part that didn't work well and this hose works great! It was super easy to replace all you need is a screwdriver,  and its a lot more cheaper than buying a whole new system. It's the same length as the original one that came with the actual system and works just as well. He hasn't had any issues so far and is very happy at the price as well. Overall, this is a great waterpik replacement hose at a great price.
