Fast shipping! They came with a case installed. Very well packaged.Although many choice to select to order heat shrink connectors like these, i finally ordered from this seller. As i think the price is reasonable which i can accept. And for those cheaper items, i am afraid that they cannot be worked as expected. However, these arrived fast and well made with high quality. I used them to connect the wires in my new house. They worked just great as i expected. This set consists of different terminals. I can use them for many functions.
