They're discontinued because they ran out. Call Knifecenter. Don't rely on conjecture. Get an answer if there's such worry.
Good gosh, if it isn't LQMT mgmt that's awful, it's their products that are a piece of junk. Never seen such miserable shareholders when with the promise coming out of the Engel Symposium has turned a penny stock, totally speculative play into a company backed by Engel creating legitimacy, credibility and hope. But yes, Engel must be out of their minds and/or the Symposium was not really held. Why hold a stock you have no faith in? Dooming it to failure is a smart move? Wanting to see your own money in your own investment in LQMT fail because you think mgmt are corrupt and clueless and awful and manufacture junk? Yikes. GL.
