I too found the water flosser too heavy and bulky to maneuver. I agree that the on/off and pressure controls are too close together.
I contacted support for a return and refund. They said they would get back to me. I was advised by email that they would "look into" the situation, but I am afraid of missing the deadline for return and refund. I am not able to send a picture of the product. I also received a second mailing that included the same product.
I asked customer service for return and refund information and have yet to hear back.
