Fully insured
You're protected.
Hosting a machine should carry zero risk for your business. Lambda Vending carries commercial general liability insurance, and your business gets documented protection before a machine ever arrives:
- Commercial general liability through The Hartford
- $1,000,000 per occurrence / $2,000,000 aggregate
- Products liability included
- Your business added as an additional insured — certificate of insurance provided
What “additional insured” means for you
If anyone ever makes a claim involving the machine, our policy responds — not yours. Your insurance is never touched, your deductible is never paid, and your premiums are never affected. And it isn't a promise: the endorsement gives your business direct rights under our policy, documented on a certificate you receive before the machine arrives.
