Anyone else concerned by what seems to be horrendous Neptune Apex reliability? My Apex unit has died for the second time in 8 months, last time it took them two weeks to replace, doesn't seem like its going to be any quicker this time! Last time I was too happy that they warranty replaced my sparkling new weeks old unit with a scratched and dirty reconditioned box. They've already had to replace two optical sensors that went rusty in the sump. My Neptune experience to date gives me little confidence, both hardware and support have been very poor.
