My Best Purchase Yet- No Regrets!!!
My best investment yet. I was looking for an electric toothbrush that was cute and practical. I have a smaller sized mouth/bite and had so much trouble reaching the back of my teeth. This toothbrush has the perfect sized head and bristles to give me an efficiently clean brushing! Every item included (the case, spare brush head, toothbrush stand, and charging cable) all are of the highest quality and the cutest style. I am so motivated to maintain my hygiene and brush with Miffy every morning and night!

So cute and works great!
I LOVE her! Miffy is my fav and when I saw this I had to get it. The travel case it comes with is super nice, and I appreciate the little black circle stand it comes with. Its pretty soft bristled, if that matters to you. Only complaint/issue for me is that the brush head is kind of small. It's probably meant more for kids, but it still works just fine for me! The vibration it has works well too.

Travel toothbrush
It’s super cute and works fine. It’s easy to use and charge and mainly works as a travel toothbrush.

very cute
i don't have a baseline to compare to since this is my first electric toothbrush but it works pretty well I think at least in making me excited to brush my teeth (I've been brushing an extra time recently so 3 instead of 2 times because I'm just so excited to brush...) the manual is pretty hard to read, it looks like it was machine-translated from Chinese to English so some things are unclear to me. for example, I didn't know that the vibrations pausing every 30 seconds were a feature intended to tell you to switch to a different part of your mouth. initially, I thought something was broken or that it was low battery (nothing is mentioned about this feature but is common amongst electric toothbrushes). 1 star cuz it works (I can't compare with anything else though btw) 2 cuz its adorable and makes me excited to brush -1 cuz the manual is kinda hard to read and leaves out a feature, would do -1.5 1 star because of accessories so 4 out of 5 pretty good especially for nijntje/miffy fans

This is a fantastic brush!
The design is so adorable, so if you love miffy get it! The battery life is pretty good! The price I got it for was good. It has around 3 modes of brushing, its functions are easy and good to understand.

Miffy is the winner
Excellent product. Holds the charge a long time, cleans my teeth well and it’s Miffy … what else could I ask for.

Not an electric brush
Cute, love that it comes with a thing to store and something to make it stand but is not really an electric brush, it's just vibrates without real purpose

Must buy!
Love how portable the toothbrush is! It’s easy to charge, and I love the toothbrush holder it comes in with! There is also an extra brush tip!

This tooth brush is very very cute ! However, it is a bit misleading as an electric toothbrush and it feels more just like a vibrator in your mouth…. As well as the bristles being a bit too soft in my personal opinion.

After reading some reviews on here I was a bit skeptical but I am pleasantly surprised with this adorable toothbrush. I travel on weekends 90% of the time and the travel case is so handy! I can’t comment on the battery life quite yet as I’ve only had it for about a week, seems to be totally fine though. Now, it does kind of feel like a vibrator, kit necessarily a bad thing, feels really nice on the gums and gives a good clean My only complaint is I wish they offered hard bristle replacement heads. I like the soft bristles but sometimes I just prefer former ones for a deeper clean.

This broke after two weeks of use, to the dismay of my teenage daughter who love Miffy. It just wouldn't charge or turn on at all. There were some problems with customer service/seller in returning the product. But eventually was refunded the cost

It's cute and compact but the vibrations are so strong it gives me a small headache. There's 3 different vibration modes and the lowest makes it more bearable. I would still definitely buy this because Miffy. ('▽`*)
