Product review (5 stars): I would definitely recommend this product for any DIY
I was skeptical of buying this product, at first glimpse. Come to find out it help me locate a leak in my refrigeration system line. It was the drain heater section, located under the frig that the water drips to, that had a couple of pin holes. I now in the process of ordering the Drain heater section and AC vacuum pump so I can get the refrigerator working, again. I would definitely recommend this product for any DIY.
