Safe Deposit Box Insurance

I know this question has been asked before, but many of the posts on this topic are several years old, so I'd like to ask again. Does anyone have recent experience with companies that insure the contents of bank safe deposit boxes?
This site lists a number of insurance providers, but I'm hoping that member feedback on this forum will narrow down the choices a bit. Here are some of the providers.
ANA Plan with Risk Strategies (formerly Hugh Wood)
American Collectors Insurance (ACI)
Collectibles Insurance Services (CIS)
Chubb Group – Valuable Collections Insurance
Safe Deposit Box Insurance Company (SDBIC)
Thank you,

I have used Hugh Wood, Inc for years, but have never had to file a claim. They are simple and painless as far as dealing with information and payment of my premiums.

I use Collectibles Insurance Services (CIS). They're great.
Unfortunately I have had to file a claim before, but it was a very easy process and my claim was paid promptly.
