Ittecc (923-0439 I/O Board w/USB, Audio, DC-in 2 Replacement Fit for Air 13" A1466 (Mid 2013, Early 2014, Early 2015) 820-3455-A

I know these reviews can be misleading. This was the right part, it fit, it appeared to be of reasonable quality. It is odd that it is now not even allowing the power from the wall plug to reach the machine. I am going with a 4 because I think a vendor selling these items should have links to debugging aids that help us know if their product was the weak link or not. I am going to try a different vendors part next. I hesitate to review too low, but the fact is this isn't working for me.

You have to be cautious when ordering used parts/pulls, especially electronics since you don't have a way to test them before you drop your money. These guys made the exchange simple. I got a great used part (and of course they got my money ;) ). Item was easy to replace and I had a note from them to contact them if there were any issues.

Board worked. There were other problems with the computer but the board allowed us to access the on board storage and rescue data.

Great product and service.

easy to install and work 100% perfect

Everything was good with the vendor and the part works very good.

This worked like a gem! Purchased and installed with no problem at all. Thank you very much!

Worked fine for 2014 macbook air
