Not everyone likes to think they will need support when they buy a product. We have experienced only a few minor issues that support has been able to help us deal with right away. We receive phone calls to check on us to make sure the 920 is doing as it should, phones calls telling us it’s time to update & how to do so. That to me makes support priceless & the folks at Lite-Check have done an outstanding job of supporting all my folks here at Best. So, with all that I just want to say thanks for the 920, thanks for opening our eyes on a new & better way to do our jobs & thanks for the support & confidence you build with your customers in knowing we have folks we can count on should we need them.

The LITE-CHECK equipment is great! It expedites the process of inspecting lights and ABS faults and time is money.

Love the alarms to lets you know when there is a short or open. The ABS diagnostics make short work of finding problems before they are a problem. We check stored codes at every service and can find intermittent problems before DOT finds them. The remote makes checking brake adjustment twice as fast as before. The Tech can operate all aspects of the brake system while under the trailer.
