I have a Cloupor dna 30 Cana clone as well. Had it for a three days now, and it's working perfectly with non of the little flaws that even reviewers have had. To Bepalmer, I think you inserted the new batt backwards which fried the chip. There is no reverse batt protection, so the batt must be inserted positive side up. If not, the chip fries and will need to be replaced
