While no one may have come out and directly said it was an HF issue alone, very clearly there are a couple replies that at the 'very least' imply it to be an HF quality issue, to the point of it being also typical of such. And also very clearly in this thread, I'm not the only one with that observation.
Of course, after a multiple follow up listings/links by several knowledgable members with no anti-HF agenda, of other such recalls by many other companies, some US based, with the same/similar specific issue, some crow had to be eaten and at least one attempt to redirect specifically from HF to it's manufacture point. The same poster also very recently continued similar HF drill commentary over into the recent HF float charger thread on this board lamely attempting to take the thread off topic.
To the topic, clearly now thanks to the OP and other knowledgeable members here, the posting of the recall with the intent to inform Bitog members, has been put in proper perspective despite some attempts to make it appear to be strictly a HF/HF drill issue.
