Query: Don't buy anything from mintek

First off, let me correct some other reviews. Mintek does have a website.(www.mintekdigital.com) HOWEVER, that's not going to help very much. For returns or problems you have to call them. I have called about a dozen times and I always get the voice mail of one of two different people. Neither of them has called me back. Evdently ONLY TWO PEOPLE WORK IN CUSTOMER SERVICE FOR ALL OF NORTH AMERICA! My problem is that the power suplly burned up. Without the power supply you can't charge the battery or run the unit on A/C power. What's worse, even if I wanted to bite the bullet and just buy a new power supply I can't because the item isn't listed. Stay away from Mintek.
