they are so nice.
I bought previously the complete device but the ribbon was very weak, I bought all the set and in 6 months the ribbon was broken, I told him to send other in warranty (only the ribbon, not all the device) but instead of send me 1 ribbon that was very cheap he told me to buy this, it's not for the money I don't care to pay it, but he doens't give any warranty at all if it breaks even in little time.
