Sarmocare/Sonic Care Electric Toothbrush is very easy to use. Does not have a charging stand or wall plug, BUT can use any USB charger. Works like any other Sonic Care toothbrush with a humming sound. It appears that typical snap on brush refills will work on this unit. 3 modes are great and easy to use/change to keep your brushing interesting. Short pause every 30 seconds and shuts off completely in 2 minutes. Charge does last a long time and doesn’t appear to get slower. Not sure if 30 days yet, but 30 - 2 minute cycles for sure. Very nice feel to the brush in your hand and I always rinse under water, but I wouldn’t submerge it although you may be able to. I love the black color and the price is well worth it. This is my first Sonic Care electric toothbrush. In the past, I have only bought Oral B. I think I’ve found my new electric toothbrush. The dentist's comments will be the deciding factor.
