Well supported product. I bought this about 2 weeks ago. When I look at Amazon reviews, after I ascertain that a product is in the 4-5 star range, I look at the one star reviews, for both percentage of negative reviews… and, how the manufacturer or seller responds to these reviews. In this case, i-Tronics had responded response to every one of the negative reviews I read, was a reason to choose this product, because the vendor was watching the reviews, and responding with an offer to resolve what ever the issue was.
