Long story cut short, I got a free electric toothbrush, Braun-OralB Vitality. Retail price is S$36.

This is the first time I used an electric toothbrush, and yeah, its true, this cleans far better than an ordinary manual toothbrush. The brush head looks tiny but looking at older electric brush models, it can be considered big already. Still, one can purchase a bigger brush head that can be attached to the body.
High end electric toothbrushes both vibrates and oscillates, this one only vibrates, and costs a third of the price of one that does both functions.
I find the brush excellent in cleaning those hidden crevices and although a little short to reach the back of my molars, it still cleans better than manual because with the traditional method, I keep hitting the back of my mouth with the brush causing bleeding. The motor ensures the brush head never makes surprise moves. Still, on the first few days of using it, my gums bled a little.
The battery life is pathetic, the manual states that a 16 hour charge will give the motor 20 minutes of juice. I have not put it to the test but after 15-16 minutes of using, it is recharged faithfully; the whole unit gets warm during charging. This is one thing you will not bring along long trips to the Himalayas.
the whole instrument is rubber coated, making it waterproof but I have found that you need to separate and wash the brush head from the body after every use because toothpaste residue gets stuck between the two parts, and not washing it thoroughly enough will leave your table with halos (see picture).
The other bugbear I have is the cost of replacement brush heads. it has far lesser plastic and bristles as an ordinary manual toothbrush but costs double or triple one.
