Hi, I just bought a new TI BA II Plus, however when press the button quickly with my two thumbs, for example from 1 to 10, this calculator shows only 1369. I have to press really slowly or with only one finger in order to be sure that all of my input are registered.
It’s not about how hard i press the buttons but the speed is the problem here, how can this expensive calculator be so slow. I’m used to Casio scientific calculator, speed was never a issue, and even the cheaper calculator from Texas Instruments (30XB multiview) doesn’t have this problem.
I don’t know if my TIBAIIplus is faulty or it’s the same for all of you. Please let me know if the Professional version or the HP 12C is faster than this.
