So, I have the Stabilo for my son (he was then 5 3/4 years) bought because he has still done pretty hard when writing and the pen has always kept quite cramped and I must say we are thrilled. The Stabilo pencil Ergo is really very good at keeping in his hand and he helps my child touches the pin loose. Learning to write (ie its name) and even simple drawings (triangle, circle, rectangle, etc.) let him go after a few exercises now much easier by hand. On top of that he takes the pen pretty cool and has him already rumgezeigt everywhere!
The only two drawbacks are, in my opinion: 1.The sharpening is a bit difficult and that need my husband or I always do and 2. The name badge is quite tiny and goes with us to just the initials. That is why we are giving here only 4 stars.
