The U12 has been an absolutely essential piece of hardware in my experimental projects. It's performed exceptionally well and I've recommended the device to several of my colleagues.

—Brendon, Electrical Engineer

Sheesh, guys. I placed this order late afternoon the day before a holiday weekend, and the best you could do is ship it an hour later? [...] My LabJack did just what it was supposed to, and at a very attractive price.

—Olin, Oxford Systems, Inc.

I don't know of many other companies that provide such excellent service. I wouldn't hesitate to recommend your product to anyone.

—Richard, Milwaukee School of Engineering

Thank you so much for your quick response. I was struggling with this late last night when I sent the request, and now first thing this morning I have a helpful reply. [...] By the way the upgrading process is so painless, it's fantastic! May I congratulate you on a well developed product with great product support.

—Jason, Compac Sorting Equipment

This [code] works a treat and I'm grateful you were able to answer my question so quickly. Rest assured I will continue to use, specify and purchase your products in the future. In fact I'm going to order another EI-1050 right now...

By the way, I'm really impressed at the level of support on the forums -- I read through quite a few questions, and you guys really come through with the answers, and pretty FAST too!
