Home Warranty in STR

[Zak House]

To protect my investment I always get a Home Warranty for rentals.  However, with my 1 short term rental I am struggling to remain confident that this is the right strategy as when something does happen it seems I lose at least a couple days with them dispatching and then following up.  At this point you have 1 upset guest and it can roll into your next set of guests. 
Do I just have a bad home warranty company (Fidelity National) or is this just the reality for STRs?
