Purchased one and got it 4 days ago.. I don't know if it's really worth it or not. Yesterday, very bright sunny day, the thing seemed like it didn't know where to go. Pretty much stayed at the deep end and went forward and backwards, not even going anywhere but 4 to 5 feet. Is the bright reflection stopping it from going? Flying backwards way past 10' and losing some debris also. Maybe defective? How do you guys like it?
