### 5/5 — Great support

*2017-08-27*

Wow! This team has amazing support and will go the extra mile to support their product and provide an amazing and incredibly useful app that helps make field engineers more productive!

**Developer response:** Thx for taking the time to leave us feedback. We feel the love.

### 5/5 — Very Handy!

*2017-08-08*

I love that the device Oscium produces interfaces with the devices that I have. I have the iMSO-204. It works all the time, every time. The one downside to the product, that the bandwidth is a bit on the limited at 5Mhz. For someone like me who deals with low voltage, small signal components, it's prefect. As far as the application goes, I really like that I have a touchscreen oscilloscope in my hand that I can carry literally anywhere! All adjustments are a snap when it comes to time and voltage per division, triggering, etc. I thought it was cool in a device this small that on top of having a dual trace scope to work with, there are four small traces so you do some data analyzing. Overall, great product!

**Developer response:** Love the five star review. Thank you, demon_moose, both for the rating and the feedback!

### 5/5 — Fantastic

*2014-11-29*

I am an electrical engineer, and I have used this while traveling the world.  It has been a great pocket pocket o-scope!

**Developer response:** Love it. This makes us smile. Glad to hear we're able to sit in 1st class with you as you travel the world! :)
