The route has seen only a handful of repeats in the last 22 years, and despite a couple of visits, Adam Ondra hasn't managed a clean ascent.
Adam commented on Planet mountain:
"The world's first 8c+, which could be easily even 9a in my opinion. It is not the most inspiring line, it seems more like a boulder problem with a rope and easier topout, but one must admit that it is of revolutionary difficulty for its time and I believe that it isn't by any means easier than Action Directe, the world's first 9a established a year later..."

Steve McClure, one of the UK's top climbers repeated Hubble in the summer of 2009 and commented to UKC:
"If it was a boulder problem it would be Font 8B. It is a boulder problem really, it just needs a rope. It's only about 7 hand movements, 9 if you're short. After that there is a breather before a relatively easy section, still around F7c+ and very drop-able."
