Title: Please sell your patent to someone else
Review: I have gone through a few of these. First one never worked. Second one worked fine with only one battery change for one year then died. Current one worked for two weeks and then drained the batteries. New batteries were placed in and were also drained within two weeks (they claim batteries should last 1.5 years). I am trying to exchange the item under warranty but it seems their customer service is intent on trying to convince people otherwise. They need to release their patent rights and allow other companies to improve on their design. This is the only product I know of in this price range, but $50 wasted is too much.
Is the review positive or negative?
