    These are wired up BACKWARDS! At least the ones I received were – the opposite polarity to every lipo battery I’ve ever bought that had a JST connector on it, and every model I’ve ever bought that was made to be powered by one.

    I used the first one of these today, to add a power lead to a project I’ve been working on for weeks – and totally destroyed it. I’ve spent the rest of the day trying to de-solder components, to rescue what I could.

    These have been the biggest waste of my time, my patience and my components. If I could give a lower score than one star I would – about minus one thousand seems fair.

    After waiting for just about a month for my order to finally make it here, all the male connectors were missing from my order of this item. From the order of 5 sets, what arrived was 25 female connectors. Incredibly frustrating. I would not order again from Electrodragon, I’ll stick with DFRobot. They’re shipping is way faster, and they have never messed up an order for me. I took a chance here because they had some parts DFRobot didn’t currently have in stock, and I got bit in the ass.
