Good Quality!

I bought a cheaper one in China. It was broken soon. Then I finally got this. I have to say the quality is really what I want.

Great Counter!

I’ve been using this style of counters for many years doing laboratory services. It has a smooth button action and accuracy. You won’t be disappointed!
