Hmmmm ....where do you start with poorly designed stuff?I suspect anyone that has given 5 stars either sells these or only had it for a few days.I received my mine, it too had been opened previously.Oh well, tryed it anyway and got it to work a little bit.Never got it to work remotely, meaning unless your phone and the unit we're on the same wifi network then "No Go".After a little bit of use the unit wanted to continue to go to the right, so if you wanted to keep going in circles you might get a little more use out of it.Concept is great, implementation has lot to be desired.Software only has 2 1/2 or 3 star rating.Learned a lesson on this one, before you buy any of this type of product, find out what app it runs on and check the rating.It would be a good indicator of how well you can expect it to work.In short, KEEP LOOKING.
