More than pays for itself on a daily basis.
Network Error
Accurate but hard to use User interface
Not useful
New Point System is not good
1 star for unecessary popups and no explanation
Zzz
Better than nothing
I paid AND this is a scam
-> yes it works perfectly 3 stars!!!!
It's a scam
And so I tested with a bad old copy of a silver coin (5 French francs from the 19th century) where I can hear the difference with sound (I'm hard of hearing) -> it works perfectly....
I want my money back, it's a total scam!
Disappointed
After paying $30 for the device, I expected more options.
Subscription plan likely limiting sales revenue
Subscriptions are generally reviled, so, perhaps you could increase your revenue by figuring a way to segment your prospective customer base.
Maybe a one-time fee for just the *custom* tester (i.e., no access to the coin library).
Or maybe:
One-time fee—say, $9.99—for access to the current database but some additional fee for the annual update (heck, and even a $1.99 annual “maintenance fee” for a “Basic” plan).
For example, I don’t buy rounds; I buy old silver. I’d pay 10 bucks for the current library, but I have no need for annual updates. Let those who need them have the option to buy them.
More money is made via a “Volume, volume, volume!” strategy than by exclusionary pricing. How many new “casual users” could you entice with a lower-priced “Basic” plan?
