There was a problem filtering reviews right now. Please try again later.
After using the adapter for awhile, there are two improvements that would make the product even better. 1) the cord from the wall socket to the plug in terminal is a little too short. I find myself having to sit fairly close to the plug in when using the adapter. 2) partly as a result of (1), the terminal is a little loose fitting on the extension from the plug in and has a tendency to disconnect--I may tape it so this doesn't happen. These aren't deal breakers--just suggestions for improvements.
Too long a review? Yea, too long a process to find the right adapter too. Save yourself the hassle and buy this one.
PS: the polarity goes both ways very easily. Don't get thrown off by the reverse polarity verbiage.
