Review (5/5): Works well
I have been using a rechargeable/cordless Waterpik which has lost a lot of power over the past year. I used the travel into first and it's great for taking on a trip. Nice and small with a travel case. Works well. Actually seems more powerful than the full-size unit.
Both reservoirs hold enough water to do the job. Happy with this purchase and it's cheaper than the exact same package that I saw at BJs by $20.
