Quality seems great.
From the manufacturer:
Brewing is a sight to behold. That’s why we created the P5 - so people can see the magic of the ESPRO Press at work.
The P5 takes the classic sophistication of a traditional glass French press and perfects it through design and technology. Simply put, the P5 is safer, more durable, and keeps beverages warmer than other glass presses on the market.
We invented a patent-pending Safety Lock™ to completely secure the glass inside the steel cage, and finally eliminate the industry’s issue of glass slipping out while pouring. We designed the German-made Schott Duran® glass to be 40% thicker than a traditional press. And we included our patented double micro-filter for a clean, delicious cup with none of the typical grit and mess.
