Nice to see that it has a good rating on ICObench, this will help the project get more investors due to its good ratings from different rating sites. I just wonder why someone put a rating of 1 on products, maybe you should try to contact the guy to re calculate and fix his problem with the project to get much better rating.
It doesn't matter whether the ICO ratings are good or not. I mean, most of them are actually not reliable. There's been a lot of cases when the project gained a lot of good reviews but in the end the project was not actually realized. Kepler is a well established company so there's nothing to worry about, I reckon.
Meaning to say that we should not totally trust the rating because it is not 100% guaranteed. Although it helps the investors to decide but they also need to go through deep search about the project. Kepler created a concept that will help humans to make their works faster and make things easy to do.
