Good product and excellent price and excellent delivery

So far so good. However, I don't know how to change between the 4 different modes. the points are there but they can't be pushed.

I thought the item would be more like the brand name. This has no weight to it. This only vibrates so you have to move it around like a.manual toothbrush. That's hard on your hands. The brush is very small (like a kiddie toothbrush) and the modes are difficult to see. The manual has really tiny print. I might enlarge it at the copy store. I prefer the brush that scrubs with movement rather than (sonar?)
