Great product and great price

I've been looking for this set to go on sale for a while. Received the item quickly, and the quality is great for the price. I have had cheaper ones in the past, and they just don't hold up. Having the built-in probe holder on the back of the voltage tester helps keep things neat and organized.

Klein is an excellent tester kit at the price.

Klein tools electrical test kit MM320 is an excellent tool kit to have on hand for circuit testing. The testers are especially useful for testing circuits after power outages due to storms. The price offered by Walmart is very reasonable compared to other vendors Shipping was very fast.
