HP 41

excellent stability for professional work, the real feeling of touching the original. And the best of the story: your HP 41 is every time with you, smart and elegant!

HP41 Kult

Meinw Ingenieurausbildung machte ich mit dem HP41-CV bzw. mit der UPN. Dabei bleibe ich. Es gibt keinen Grund zu wechseln...

Sehr gut

Funktioniert perfekt, nur das Starten der App. Dauert VIEL zu lange. Wegen allem Anderen: Fünf Sterne!

Perfect!

As wonderful as my 1st 41cv when I was 18 (now 53). Thanxx for this collector's calculator! Didier (CH)
