I love the compactness of this waterpik. I had the larger one and this one is far more convenient. You don't have to invert the reservoir and the power of the jet is actually stronger than the bigger model. Granted, the smaller amount of liquid in the reservoir was a little disappointing, but I just keep another cup ready to refill it while I am still using the pik. It is definitely easy to use and, of course, that means it will be used more often and the check ups at the dentist attest to the positive impact it has. I most often use a salt & warm water solution and it works great.
