## Less suited to

## Customer feedback

Customer feedback is mixed on quality and value. Some customers find the pens good, while others are dissatisfied. Reports also raise concerns about durability and ink running out quickly. That matters if you need dependable pens for repeated or extended projects. The dual tips and water-based ink are listing claims, not evidence that customers praised those features.
- Negative themes: Customers report that the pens may not last long and that ink runs out quickly.
- Mixed feedback: Customer opinions are divided on pen quality and value for money.
