[This review was collected as part of a promotion.] The USB charging is not the most convenient - you actually need a hub or charging block where I charge it and my space does not allow for it! Not my favorite feature, but I love the brush otherwise and am 'dealing' with this inconvenience. First world problem right?!! Ha ha!
Bristles are comfortable, handle could use more 'grip' and a bit thinner. I like the speed settings, and they are easy to manage and I don't feel like I am damaging my gums while using it. I am left with a thorough and fresh clean result every time I use it.
[This review was collected as part of a promotion.] I have purchased this item for the past 23 yrs. I have had only 3 in that time period, so that proves its reliability. I cannot leave home without it!
[This review was collected as part of a promotion.] Very nice product. Much improved from old design. However, pressure sensor is not well described, particularly whether/how it resets.
[This review was collected as part of a promotion.] 4100 series electric toothbrush. This is an excellent product, especially for a person with gum disease. My teeth are perfectly clean without applying any kind of pressure. I highly recommend this toothbrush.
