The best part about using this software was that it made our work much easier than what we had done earlier with different softwares which were very slow to run or even crashed from time to time due too many errors in file inputting etc! No issues at all as far I can see but if you are looking out something other then just speed of execution please look elsewhere because there might be some better alternatives available!! But yes its good enough considering cost involved by most companies who want their employees trained properly so they dont have any hiccups once hired! The ease of use as well as its performance are two things that I like best about this tool. Also it's free! Very good product to work with if you're looking into Data Science or Machine Learning in general. Nothing really at all. It does exactly what we need it to do so far. We've been using it since last year when our team was still small (less than 10 people).
