I was not sure if the files are fully supported for all 3D Softwares as advertised. For the moment all was OK! worked! it was easy payment, 3D Models World is a great place (better deals than other websites) I wish they will add more 3D Models.
My fear is that I would not be able to scale down the parts of the 3d model. but I was able to scale down the parts to a working size without any issues, purchasing the items through PayPal was quick and easy, If you need a file and it is on sale, go for it. models are well done!
