Excellent buy Review by Mickey
I had a single trace DS201 with just a plastic case and though it worked well there was no RF shielding and the need for more than 1 trace brought me here.

This DS203 with several ports is way ahead. Portable good battery life and easy to use.

Only had it for 10 days and will be ordering more for the office.

useful and tiny Review by Wilson K
It is a good pocket size product. Amazed at its features available: analog channel * 2 digital channel, controls by 4 button and 2 scrollers, etc.
The function of the oscilloscope and its size is strong, it is practial and convenient to carry. So it is worth investing time to learn how to use it effectively and efficiently.
I really like this device and I believe that it will making a great progress in the firmware upgrade comparing with the previous version. Good purchase. (Posted on 5/6/2017)
