Review: Great little connectors for projects - Excellent product, very good value for the money. Mine was opened already and 3 of the green plugs were missing, so l assume it was a sneaky return and restock item, but that's not the sellers fault and doesn't change the fact these are great. desertcart is terrible about return items that way sometimes. I only needed three of the 6 pairs anyways, so it's fine by me this time. Great item, good quality, fast shipping. Bang for buck exactly as expected.
Review: Great, cost effective barrel jacks - I purchased these barrel jacks to use with my power adapter. They did not come with a wiring diagram, and I guessed wrong the first time - purely user error. As soon as I changed the wires, the jack worked exactly as expected. They were resilient to heat (while soldering). These barrel jacks were even packaged in a small plastic box to help with organization.
