We are using sama data set for our project. It has very rich attributes which can be used with deep neural networks architecture efficiently. I am working with them since 3 years now without any issues or complaints so far. They have good team of experts who provide support when you need it. Nothing much to dislike about their product if they don't charge too steep price and give some discount during sales events like Flipkart etc. You should go through few tutorials before buying from there because your expectations may differ than what we get at first time. We use this dataset for object detection projects where we want to find specific objects within images/videos that helps us analyze different scenarios (like traffic congestion).
