I have had two because the first one had a catastrophic failure in the field. The second one now has a slow leak I can't find. MSR will replace it but what an absolute pain. In regular form it is also too narrow and the sides do not hold enough pressure. No surprisingly, MSR is coming out with a version with stiffer sidewalls next year.

Much like the Hyperflow, I believe this product simply needs more design work.

I am not sure what my next pad will be - still searching.
