We ordered 30 for the church and a week later 6 more for the house. Two out of 36 were delivered with manufacturing defects - there was no "knob" of the inner conductor in the (plug-in) terminals (see picture). I emailed DiCUNO with an explanation and photo and Helen was quick to reply with an apology and immediately sent 4 more good ones to replace those two. These extensions appear to be of excellent quality (except for the two that passed factory quality control) and they work well for our purposes (using high brightness PAR 38 LED spotlights) and at a great price! I will buy from them again every time I need any of their products. Manufacturing defects can happen, but Helen's excellent customer service more than makes up for it!
