Looks like the impact wrench has a very bad review on Amazon: http://www.amazon.com/PowRyte-2in-Rocking-Impact-Wrench/dp/B00AK15Q1M
Workshop brand vacuums are basically the same as Ridgid and Craftsman shop vacs. They are all manufactured by Emerson Tool Company. They also manufacture the line of GoClean household wet/dry vacs.
These air tools are about an order of magnitude cheaper than comparable name brand gear. Tempting, but still probably too good of a deal to be true.
