As functional as a Water Pik but much less expensive
These questions about battery life on products recently bought are ridiculous.  We haven't owned them long enough to give a legitimate review on battery life.  Otherwise this is comparable to a WaterPik but much less expensive.  If your dentist recommends a WaterPik and gives you a coupon for an inducement, consider this option.  It drops the price below getting a WaterPik even with a coupon discount.
