    Review by Mike Bunnings (Posted on 24/02/2009)
    Hey guys, it's not often I leave reviews for products but I was so impressed with your fast delivery I couldn't help it! I only ordered the product at 3pm and it was with me by 9am the next day. I hunted around online and you had the best price. The unit is simpler to use than I expected, a handy table on the back of the checkbox shows resistance values and tolerances. Luckily my PAT Tester is in spec but I can now check it on a regular basis. I'll definitely be back next time to order from you if need some pass labels. Thanks again.
