Bad product, horrible customer service useless system. I wasted about 6 hrs with this company. You buy their products to make life easier, well in my case it made my life difficult. The product would not work properly, keet going in circles and after 1 or 2 minutes go back to dock. Customer service could not do anything about it, have to drive several miles to the store I bought it to returned it. I supposed was going to have a replacement for a discount price, but their system would not work so I could not pay for it, their answer? just call again and waste more time with this useless brand.
