I bought my IRISgo coffee mug from a local Müller store in Germany. Before buying it, I spent quite a lot of time comparing different brands, and I'm glad I chose this one.
The mug keeps my coffee tasting fresh without affecting the flavor, which impressed me from day one. Unfortunately, after about four weeks, the silicone twist lid got damaged. I was disappointed, but I decided to contact IRISgo through their website.
Their customer service exceeded my expectations. They understood the issue immediately, handled everything quickly and professionally, and sent me a replacement mug with a fresh 2-year warranty. Since then, I've been using it without any problems.
Great product backed by outstanding customer support. I can highly recommend IRISgo—10/10!
