Mala calidad, colorido y divertido para los niños pero las cerdas y el motor son de muy mala calidad.

Doesn't occilate as fast as other brand. Battery runs out WAY too fast.

Very cool to decorate, and worked great for about 6 months, but changing batteries was a huge pain and now its dead 6 months after purchase.

not sure if it's the case for everyone. but for usthe battery ran out within a week. disappointed. without a battery it's just a clunky normal brush.

This is very cute, but I'm glad I got a good deal on it. It lasted all of 6 weeks. No way to change the battery or the head.

Yes, this comes with batteries, they last about a week. Then your kids are sad that their new toothbrushes don't work anymore. Find a tiny screw driver, switch out the batteries, close the compartment, test the brush, discover that the diagram for how to install the batteries is wrong, open it back up, switch batteries around, close it again and PRESTO! it works again... For about 2 weeks. Then they slowly die again. Lame. We've gone through a bunch of batteries trying to keep the spin brushes spinning. Will not buy again. Don't waste your time.

I didn't receive a Spinbrush with stickers like pictured. The brushes I received have a Wild Bandz decoration instead. My girls like the brush with stickers so I returned these brushes back to the distributor. Battery Life: if you are brushing a toddler's mouth the battery will probably last 3 months. If your daughter is brushes her own teeth and she bites the bristles a lot, or uses a lot of force when brushing, it will last about a month before the batteries will wear out. You have to have a micro-screwdriver to open the casing. I have three kids, and in 12 years, none of them have ever had a cavity, thanks to these Spinbrushes.
