No issues here. So far my LP reg and BCD/suit hoses have done about 800 dives and the HP 250. Some fraying on the top of the LP ones that might be an issue with a latex neck seal but its cosmetic only. can cut/burn into place if its an issue. No problems or issues with any of the hoses at all over a fairly large number of dives now (that and exposure to very hot sunshine and salt water every single day etc etc)
