Reliable but pricey

The quality is undeniable compared to cheaper alternatives. The dyne levels are precise, which saves us from production errors. Only giving 4 stars because the cost adds up when buying multiple sizes.

Precise and easy to use

Very straightforward to use even for new technicians. The liquid spreads evenly if the surface tension is adequate. A must-have tool for coating applications.

Good for spot checks

Works exactly as described for quick surface tension checks. The brush tip is durable. I wish they offered a bulk discount for purchasing the full range of sizes.

Fast shipping and genuine product

Received the size 38 and 42 pens quickly. Packaging was secure, and the expiration dates are well into the future. Great for testing adhesion before printing.
