Rather than take the chance of wasting money on substandard media, we’d strongly recommend you subject any media you’re planning to buy to a few simple tests:
• Start by looking at the media from all angles. What’s your first impression?
Well-made and sturdy? Or can you detect obvious flaws?
• Check/measure the depth.
• Handling is important. How does the media feel?
Robust yet flexible? Or paper thin, inflexible and fragile?
• Try to tear the media. If it rips easily, that’s a problem.
• Stand on it. Are you confident that it can be used to create a strong yet
flexible structure capable of withstanding, at the very least, the weight
of engineers and maintenance crews?
