Business life insurance review: is it actually too high?

We've had the same business life insurance plan for about 5 years now and our premiums feel really expensive. From what I can tell, we might be overpaying but I'm not even sure where to start comparing. Apparently business life insurance costs vary widely based on business size, owner age, coverage amount, and policy type. The question is whether we should shop around or if our premiums are actually reasonable. What's making me concerned is that we haven't reviewed the policy in years and rates might have dropped. I've been reading that shopping around can save 10-40% on premiums and that many businesses overpay simply because they never compare. What's appealing about reviewing is potentially saving thousands per year, but what's making me hesitant is the time investment. Should we shop around for quotes? Have you reviewed your business insurance recently? What was the savings like? How many quotes did you get? Is it worth the hassle? Should we switch providers or negotiate with our current one? What factors should we be looking at? Are we paying for unnecessary coverage? Would you recommend getting a broker to help? How much did you save? Should we do this annually?
