hard time finding product thru system, found you on line when I looked for the spal unit in general

Very easy to talk to on the phone and excellent service.

I ordered Thule Aero Blade Load Bars as part of a bike rack for my Infiniti EX35. The part was order on Saturday, 04/14, and arrived at my doorstep on Tuesday, 04/17. And that was by FEDEX Ground shipping. Very very quick, and the right part to boot. Excellent service.
