This arrived very quickly and is a really handy size for taking anywhere needed.
The grey and white makes this appealing to both boys and girls and because of the design is easy to use in either left or right hand with the buttons being a good distance apart for pushing down. Both myself and my young daughter found the buttons in a really good position for comfortably holding this for getting the full benefit to help stengthen both fingers and hands.
It is easy to alter the tension as your fingers/hand start to strengthen so perfect for progressing and using daily.
