Hi Slowpoke,
I have nothing but positive reviews for Watt Wagons and their customer service. My Ultimate Commuter arrived without any mechanical problems. The worst thing was a scuff on the frame that came about via transit. This buffed out easily.
When it comes to answering questions I've always received a timely answer without a need to follow up. Also, my Ultimate Commuter is a custom frame, and the customer service I received for the build and measuring process was at the very least outstanding.
If you have any questions from a customer perspective please let me know.
