While I have not made use of the online engineer support that is available on the LabJack website knowing that it is available is a great comfort as we work through our development process.

Have always found the support great. I would have given 5 stars but think you did NOT improve the website in changing. And I had to sign up again...

Response from LabJack· Nov 9, 2022
Thanks for the kind words and feedback Gary. While there is always room for improvement, I apologize our new website was more work/time for placing your repeat order. Thanks for your ongoing partnership with LabJack!
Parts were in stock. Picked up the same day

I am using the U3; this is my first LabJack product. This is an excellent product; everything worked as advertised. The support is the best I have had from a company in a long time. I highly recommend this product to anyone, and working with LabJack has been a pleasure.

Great support and sales team. Shipped everything based on our agreed timeline. Followed up on delivery. Excellent versatility, and probably best value for money DAQ in the market!

I needed help configuring the extended features of the T4 LabJack. Within a day, I received exactly the information I requested.
