Query: disappointing

I ordered the XL1500 because I am moving to China for my business. Unfortunately, I had to return the product. The voice feature is so poor, I could barely recognize the english speaking voice, much less the chinese voice. The french, spanish, and german voices were not too bad. I was also disappointed that I could not figure out how to enter pinyin chinese and radical chinese characters, even after reading the poorly written manual three times. The clincher for me was that the headphone jack did not work, it just muted the voice feature altogether. The unit does have an AC jack, but does not come with an AC adaptor. I called Ace Photo to return the product and was informed of the 10% restocking fee.
