I don't think they have anything portable for cell boosting. At work we have weboost in the trucks and we are very happy with them. I carry an inreach when I'm in an area with bad service.
I look at these often. I have the magview and always have wondered if ollin is better. But i don't want to take the risk to find out. They look like they are better.
I have seen very good results from the kudu. My brother loves to shoot bulls quartering to and the kudu breaks everything in its path. Only down side with single bevel is they are extremely hard and dangerous to get out of a target. If you are not careful they will seriously cut you.
I stepped up to 30 being my first pin 5 years ago. I love it for hunting. I do several 3d shoots for fun and that is where the 30 yard first pin becomes a slight issue. Trying to hit the small close targets 12 ring is harder with not having a 20 yard pin. I do not shoot a slider.
