bought one of these via the Kathmandu web shop and when I received it the plastic plunger piece appeared not straight and there were signs of stressed plastic around the circular compression plate. It appeared to have been cross threaded, I pulled it apart thinking I could likely screw it in straight and move on. not the case, a genuine manufacturing fault. Personally returned it to a physical store hoping to swap it over but the other 3 on the shelf all had the same issue, an issue that would have resulted in the plastic plate snapping off from the centre after a couple of uses. I would have give this product zero but the staff were entirely helpful.

I've had mine for 10 years. It works just fine. The plastic outer coating has split in a couple of places, but it hasn't affected its function. I would buy one again. Would prefer it if there was a smaller option. Bit expensive. What else can you say about a coffee plunger?
Stainless steel, strong
Plastic coating could have been done more robustly. Would prefer it if there was a smaller option. Bit expensive.
