I’ve been using the solar-battery hybrid for a couple weeks and it’s really handy for quick calculations without scrambling for fresh batteries. The screen is clear enough for my needs, and the compact size fits easily in my desk drawer.

The auto shut-off is a nice touch for saving battery life, and I appreciate that it works with both solar and the included batteries. It fits perfectly in my hand and feels sturdy for daily use.

I’m really glad the batteries are included, so I could use it right out of the box. The auto shut-off helps save power when I forget to turn it off during lessons.
