I bought this to take to a rummage sale held by an animal rescue organization where I volunteer. The only problem I had was trying to feed thin paper tape into it but finally figured it out. Calculator held up perfectly through 3 days of a busy checkout. Very happy with purchase and the fact that this machine is compact.
