It a great website but there prices are pretty high when compared with other Chinese hole sale online mega stores for example if you order a V911 helicopter from aliexpress it will cost you almost 41usd ( including shipping).
But if order the same from banggood.com it will cost you 35 usd ( including shipping) so there is difference of 6 usd and I also ordered ornithopter ( flying bird) which arrived broken it didn’t fly at all so I think you should think before ordering.
