YUE MOTION Liquid Motion Bubbler Visual Sensory Toys, Liquid Timer– New Big Calming Sensory Bubbler Toy- Colorful Liquid Hourhlass for Stocking Stuffers, Novelty Gifts

Love these for my kids. They’re fun to watch and help them brush their teeth for an appropriate time. Colors are bright and pretty.The kids really enjoy them

We have tried so many different tooth brush timers and these are the only ones that have survived! They are durable and fun!

These are working well as timers for teeth brushing, 4 stars because one of the timers runs faster then the others.

My grandkids actually spend the entire time and then some brushing their teeth the entire time it takes for the colored material to float to the bottom. It actually takes two minutes. They trade colors and brush their teeth again. Sometimes they just like to see the colored liquid flow from one side to the other. Great attention keeper.

We bought them for stocking stuffers amd they were a bit ages 3, 5, & 9. And acceptable interesting ages 10, 15, & 16.I find them very cool.

I bought these for children and teens who prefer certain sensory items. However, I must say, I find these very relaxing! I can just sit and watch the bubbles move..then flip it over and watch them again. The pink and yellow are a little more faint compared to the other colors, but for the price and quality, it's a great buy. Definitely recommend

Just bought these very cool looking timers. The design is very attractive and the 2 layers of bubbles is a very neat effect. However it came to my attention that the time was off. I flipped two of them and started a stopwatch to find one went for 3:30 and the other for about 4:15. Flipped and timed again: 2:04 & 2:17. flipped again: 3:14 and 4:02.Apart from this, they're huge and don't fit well on a counter.

One of these times for about 59 seconds instead of 120. Two out of three ain't bad but it ain't great either
