There are a couple distinct differences between the units:
1.) 20 foot cord on Shurhold’s Polisher, but other are typically only 12 feet.
2.) Shurhold's power cord has a GFCI Plug for your safety. No other polisher offers this feature. This turns the plug into a breaker like the outlets in your bathroom; it’s added protection from electrical shock near and around water.
3.) The Shurhold Polisher comes with a heavy duty canvas carrying bag.
4.) The Shurhold unit comes with many handle options. The side handle, D shaped handle, and the ergo cut head cover. At this time, Griot’s only offers the D handle and Porter Cable the side handle.
5.) How about the Shurhold support team! We are based in Florida and very knowledgable on the ins and outs of the Polisher. Our customer support team loves helping our customers tackle even their most difficult jobs by giving expert advice on Polisher and chemical use.
