Service was excellent and prompt dispatch. Even came with a courtesy pinout printout. Great to have a NZ supplier that doesn't charge the earth. Great work mate.
Positive Trade Me feedback
Excellent trader. Item was well packaged and arrived quickly. I will be buying from the trader in future - quicker than buying from overseas with a competitive local price. A++
