Brian Ellison –
Ordered from Brewkasa.com for my GS3 AV — shipped within 48 hours in packaging that clearly someone cared about. Every piece is a true direct fit, so the whole install took me about 30 minutes with just an allen key and a screwdriver. The black walnut paddle knob and steam caps are the standouts: real grain, proper weight, zero cheap aftermarket feel. My GS3 went from clinical to the centerpiece of my kitchen, and their support actually replied like humans when I had a pre-order question. Worth every penny — would buy again in a heartbeat.
