Are you speaking of warranty here? Or general reliability? I ask because sometimes one product will last just as long as another, but the mfr sets aside less money to cover warranty claims (to keep costs down), then offers a shorter warranty period simply to keep the price down. It's hard to tell which is at play when it comes to warranties, as they include elements of both reliability and "cash reserve". It's likely too early to tell this for the EG4 products, though.6000xp 5+ year unit
