I like how it can handle so many different types of routings, whether its simple or complex! It's also easy enought even with limited experience you'll be able learn what functions are available fairly quickly (this was my first project using opti!). There really isn't anything i dislike other than having to pay per month which seems unnecessary but thats just because we were unaware prior - you're billed at sign up though! So if your looking into this product make sure when signingup that they mention pricing during onboarding otherwise there will probably need some convincing as well :) We've been optimizing routes within our fleet in order to ensure optimal fuel usage/mileages. This has allowed us better insight into where bottlenecks may exist allowing more efficient workflows etc.
