### ⭐⭐⭐⭐⭐ Very happy
*by B***C on 2 July 2020*

For $10 this is one awesome pen. The hybrid Acroball ink is terrific; I think it’s better than that of the Jetstream. The 0.5mm point writes very smoothy. If it suffers in some way it’s that the ink isn’t as bold as some others but for me that takes a back seat to both a lack of smearing and smoothness. Also, the grip is excellent.
