Bests & Worsts Reviews from Amazon

Purchased August 2014 - stopped working Feb 2015 - emailed manufacturer to repair or replace under the "life time warranty" guarantee - not heard back yet UPDATE 3/15/15 - got email from manufacturer that if I would package, seal and prepay shipping the unit back to them, they would test it and if it was not working they would send me a new unit PROVIDED I PAY $29.95 IN S&H! What a deal - I pay $69 for a lifetime warranted unit and when it stops working in a few months, I get the privilege to BUY a replacement one for 50% less. THIS is a lifetime warranty? I don't think so.
