Query: worked great...for a day

I purchased this based on the recommendation from Amazon about what a great add-on this product is. It was great - the one time it worked. Unfortunately, I needed to leave the country (on vacation) so I didn't get a chance to return it the time limit. I'm glad it was less than $10 but I guess I got what I paid for. Maybe I got a reject from the factory because the other customer reviews were good.
