The microscope that you can use on your phone was an intriguing lure...don't fall for it. They will send you the microscope but not the adapter needed for the connection. Then they don't tell you about the free app you need and it is hard to find out about in order to actually use the stupid thing you just bought!! It takes weeks, no...months to get here and when you do there is nothing to instruct you as to its use. Yes, you are mad by now, but you hope you can figure it out. Ha, what a joke!! When you finally find out how to download the app they say will bring up to speed on the scope, your phone will not connect. Do you feel duped? Oh yes, you do. Nothing you do will make this come to fruition. Now...you go to see about a refund. Ha...not going to happen they have all kinds of reasons why you will not qualify for one. They make it seem all hunky dory but you have been scammed!! My first emails were just a bunch of robot replies and not one of them availeth much. The money I sent them was a total loss, please do not fall for there deceptive marketing. The facebook add which prompted me was a total farce. I am going to look into Visa canceling my payment.
