I have to say what a great idea. Seen this product on a Tic Toc and had to try it. My daughter is at the age where she is really going through her mathematics and this product has been a great investment 👍 5 🌟

    Doesn't work and second hand being sold as first hand
  

*by A***L on Reviewed in the United Kingdom on 15 July 2023*

Product is very poor quality. The wheels are too loose. The product had clearly been used already as ink was left on the roller wheels. There are too few numbers on the wheel so it only offers approx ten sets of numbers so you are constantly having to turn the wheel to create a new set of numbers for your child to calculate. There is no internal cog function for the wheels to click in to place and hold, so this means the numbers don't align properly. I want my money back but i have missed the return window. Poor product, better off getting your child to practice their hand writing and writing it out themselves.
