I'm really happy with this helicopter! It is very easy to use (although some say the manual is in English, you receive mail in French) and very pleasant to fly. You can quickly become addicted to this little "jou-jou". Level battery takes 15 minutes to charge 5 min steals, which is great compared to other products. And unlike other reviews, I'm twenty charge and he always keeps his same load capacities and steals. I was also surprised by its high strength. Indeed, he had dropped at least fifty times between the doors and the furniture. But mostly he fell three times from above a staircase and once down it flies again, was really good quality for me. However he puts arrived broken lhélice back but nothing serious because there is a replacement kit supplied with the helicopter (screwdrivers, blades, rear stabilizer and propeller). As for delivery, it arrived just in 18 days and I was able to follow up with me in Singapore through so no worries followed on that side for me.
