Product review (1 stars): Doesn't work and won't refund my money
Received this last month and have been working with it trying to get it to work, but it doesn't work-- my computer cannot find it at the (working) usb port. Instructions are not helpful. Customer (NON)service says it SHOULD work. How helpful is that? Wow, now I'm out the dough for DOA equipment. Thanks for nothing Amazon AND Extech. DO NOT PURCHASE THIS!!!
