Does anyone use Clear Token for their common area laundry machines?

[Roseann Koefoed]

My go-to coin washer and dryer repairman is recommending that I install Clear Token on my machines.  This is a device that would allow tenants to connect their phone to the machine via bluetooth and pay for their wash or dry electronically.  The benefit to me as landlord would be that I don't have to pick up quarters anymore (or less of them because machines can be configured to accept coins or electronic Clear Token payment), revenues direct deposit to my operating account once/month net of a $5 monthly fee, and there is an owner dashboard where I can login to see where my month's revenue stands.  

I'm googling and the reviews are mixed from the tenant user side.  Are there any landlords out there using this technology?  If so, I want to hear from you!!
