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.

Just got an update that my product may or may not be delivered this week, or next week, but the shipment might be short..? Update: LabJack was quick to reply. Supply chain issues continue to plague manufacturers and customers alike. Thank you for the update 👍
