I like how easy it is for employees/customers that visit our store, restaurants etc., with smart phones or tablets can see all screens (digital) at once instead only one screen per customer! The best thing about this system we are using now - no more paper tickets left lying around!! No need anymore either cash register receipt book.
Yes there could be some improvement but i honestly have not found anything yet which made me dislike something from them so far :) Definitely recommend if you want an automated way managing signs up sales information as well keep track what's available where via smartphone /tablet devices.
