I have the exact same experience as the previous reviewer. The unit quit working after a year or so. It had Err in the LCD. I called warranty service and the Indian tech support guy was quite friendly and agreed to replace it at $6.5 for shipping and processing. They only take check or money order only because their credit card system is down. It seems that the credit card system has been down forever and they never bother to fix it.The quality of this product is questionable since there are so many failures. Try to avoid it at all costs.
