Perfect!
I purchased a multi adapter and I wasn't able to use it on my device. This reversed the polarity and now it works with no issues. Caple length is the right size and seems very durable. Very simple to use and zero issues. Getting 2 for this price is fantastic and saved me buying another adapter. Brilliant!

they work
Reduces frustration level when all you can find is centre + transformers and you need centre negative however it's best to label them with coloured tape (Yellow my pref) X - crossover
