Warranty Experts is a broker/agent. They sell extended warranties from various companies but are not the insurer, so you need to ask which insurer the policy will be with and then ask about others who have that one. I bought an RV Shield policy through them two years ago and it has been excellent (I've had 4 claims so far).
BUT!!! There have been at least two reliable reports in the past year or so that Warranty Experts has failed to properly write the contracts to provide the insurance, nor have they refunded the prepaid premium. When contacted about the problem, the owner (Dave Gardiner) became obnoxious and verbally abusive. There are several more complaints about his verbal abuse, foul language and harassment of women. Google Warranty Experts and you will find some of the complaints. I would not want to take the chance of doing business with them.
